Problems with turbo memory - ianvstor.sys

Until last night, my T61 was pretty stable, even with Turbo Memory activated. I had previously changed the power saving options that caused hangs while using the notebook on battery power. I have the latest TM driver from Lenovo.

Last night my computer suddenly blue screened. I didn't get a chance to read the screen before it attempted to reboot. However, as Vista was loading, it blue screened again. It was complaining about 'ianvstor.sys.' This continued as I tried booting into safe mode and selecting various options with rescue and recovery. I could not get my T61 to boot at all before it crashed again.

Finally, I booted Knoppix from DVD and mounted the Windows partition. I renamed 'ianvstor.sys' in the \windows\system32\drivers directory, and rebooted. This time Vista booted without incident. Vista automatically disabled Readyboost and Readydrive because it could not locate ianvstor.sys. (because I renamed it).

I have left it disabled for now. Hopefully, this will help someone else who may encounter this problem where the system cannot boot.

Has anyone else had this problem? and have you found a fix?

 

Intel has an even newer Turbo Memory driver than Lenovo offers. Maybe try installing that.

 

No problems yet, but I am beginning to think that Turbo is like a timebomb ticking away inside my TP...

 

I am beginning to think it's not worth the risk to use Turbo Memory until it matures more. I was worried I would not be able to recover without reloading Vista. I haven't tried Intel's driver since my system has been stable for a few months.

I think there's a reason Lenovo doesn't have the latest and greatest drivers. I allowed Windows update to load new drivers for my nvida card. Occationally, the video driver would cause a blue screen. I have since reloaded the version from Lenovo, and haven't had any problems with it.

 

Get the latest drivers from Intel, initially I've had these problems as well but now it's fixed. I have not had a blue screen in nearly 6 months.

 

disable the hybrid disc power saving option in power management

 

Hi dayphx, I've just experienced exactly the same thing: blue screens etc. and it won't boot even in safe mode.

Anyone got any advice on what I can do - is there a fix? The last thing I want to do is format!

Help

 

Does the hybrid disc power saving cause this error?

 

I haven't the faintest idea, I just launched an application and got the blue screen, it went downhill from there...

It's definitely referring to a problem with iaNvstor.sys

 

I've downloaded Knoppix and have booted from CD, located the iaNvstor.sys file in Windows\System32\Drivers directory but when I try to rename it I get an Error saying it cannot be deleted. Could anyone tell me what I'm doing wrong please?

Thanks

 

Do you have the latest version Intel Turbo Memory Driver?

 

Yeah, I've downloaded it just now (onto another (this) pc) from Intel's site. It's an exe but I can't run it on this pc as it says it's not compatible.

I thought I was getting somewhere using Knoppix, I thought I could just rename the driver .sys file but it just won't let me.

 

Knoppix normally mounts the Windows file system as 'read only.' You can enable write mode by right clicking the icon on the desktop after you mount the file system and select the option to enable write mode. I don't remember the exact wording, but it should be obvious. Then you should be able to rename the file. Good luck.

 

Thanks, I'd looked at permissions etc. in the actual file but that didn't work, I never thought of looking back at icon level.

Just tried it and now managed to rename the sys file...and it's booted up fine. I'll try the new driver now I think.

Thanks for your help

 

You're welcome. I'm glad you have it working again. I shutter to think how many people will resort to reloading Vista when they encounter this. Let me know if the new drivers work, and what version you end up using.

 

So far so good, the driver is version 1.5.0.1013 got from Intel. I've deleted the renamed iaNvstor.sys file (as obviously it uses the new one now) and it's running fine.

I've loaded the application, which caused it to crash the most, a few times now and (dare I say) no problems yet. It's strange but whenever I got the blue screen it would always be ok after reboot, it was just today that for some reason it died.

I'll post back here if it starts playing up again.

 

I am using the latest driver version from Intel.com on my Dell Precision M4300, and BSODs with ianvstor.sys still occur randomly. I however think that it may be related to my complicated setup, I'm running 4 monitors on my laptop via a video card in my docking station (2 monitors driven by external video card). I believe that this unorthodox and little used configuration is causing conflicts but am not sure. I've sent memory dumps etc to Microsoft by reporting, so hopefully this can be solved. I did discover that disabling readyboost helped reduce the BSODs by roughly half. So until drivers become more mature, I'm only using the readydrive feature. Also, the BSODs either happen at bootup or don't happen at all. If both readyboost and readydrive are disabled, I don't get the BSODs, and undocked, the computer seems to run stably as well.


(Edit) *whoops I just realized this is a Lenovo forum - so I apologize for the post. But yes other computers do have similar problems with ianvstor.sys

 

If anyone could please help me that would be great:

Today out of the blue (no pun intended), I am getting repeating BSODs on the ianvstor.sys Turbo Memory driver on my T61p.

I've managed to boot up on Knoppix 5.1.1 and I can mount my Vista partition, but can't change the read/write mode to write because I get the following error:

The remount command failed. Maybe there is another process accessing the filesystem currently.

I think this is because Windows didn't shutdown cleanly, but since I'm in a never-ending BSOD loop, I CANT shutdwon Windows cleanly.

I just want to delete/rename the ianvstor.sys driver, so I can boot up and disable it or update the driver.

Does anyone have any ideas?

Thanks!

 

Have you tried the steps posted above?

 

I couldn't get Knoppix to work, but I was able to use a Vista install DVD to solve the problem. The system autorepair failed but it offered me a command prompt from the advanced options screen. From the command prompt I was able to rename the ianvstor.sys and reboot successfully into Vista.

 

Glad you got it going again. As far as the error you were getting, it may have been because another process was currently accessing the file system. Before changing the read/write mode, be sure to close the file manager window, and any other application that may have the file system open.

 

Hello,

I did exactly what was mentioned in the earlier posts:

1. Used Windows Vista DVD to get to the "ianvstor.sys" file as described by Jetsetter and renamed to ianvstor.sys.old
2. Installed latest Intel Turbo memory drivers.

After that, I noticed that "ReadyBoost" had not been enabled in the new installation of intel turbo memory configurator. I enabled it.

Doing all this, I still get the BSOD. One change is that, I can at least boot up after the BSOD, but don't know for how long before it starts crashing right at boot-up.

Couple of points: I am using Vista 64-bit on X-61 tablet.

Any ideas?

 

Install the latest turbo memory driver...i believe it is dated november 2007 something

go to power management and disable the hybrid disc saving option under "hard Disck" in advanced power options. Make sure you do this for all 3 pre-configured settings

you should be set

 

Hi All,

I got the Asus G1S-B2, and I too am getting the BSOD. I originally thought that the problem arises from my nvidia 8600m gt driver (asus is too cheap to certify the latest driver from nvidia, so it is not available), so i upgraded my video driver from laptopvideo2go and the bsod did not go away.

althought the BSOD is sporadic for me, it still pisses me off. so i did some digging and it turns out that the latest and greatest turbo memory driver from intel has known issues, few of these known inssues are BSOD's.

Please see this release note from intel:
http://downloadmirror.intel.com/14824/ENG/ReleaseNotes.pdf

In any case, I think it's a matter of time, when these technology matures. I'm hoping the next intel driver will address this BSOD problem. Until than, not much we can do, unless we just disable the turbo memory.
