My co-worker's computer (around noon time EST) decided to do some BSOD. It is 0x8E pointing to iaStorv.sys (Intel Matrix). His data volume is a 4 drive RAID5. It is healthy in the RAID BIOS. The computer will BSOD after being in Windows after about 2-5 minutes. Logging into the OS is not required. Safe Mode works fine, even when accessing (copy, move, delete files) the RAID volume. I have already updated to the latest driver for the board.

OS: Windows 7 Enterprise SP1 x86
Board: Intel DX58SO

The same BSOD happens with either driver. He has already tried a previous restore point without a problem.

His PC does not have the debugger installed, and it won't let me install it in Safe Mode due to a DCOM error with MSIServer. So I had to analyze on my own PC.

Other than updating the drivers, I can't think what else to try, and I'm not sure what I'm looking for in the dump. Any ideas?

I've got 2 of them, but we are not ruling out a problem with the HDD. The second dump I gathered was when I ran Gmer on it just got kicks. It reported a failure to read MBR on Disk 0 on the initial scan. I do not think I ever ran Gmer in Safe Mode before, so I do not know if that is why I got that error. I was unable to write down or screenshot what it actually said, because then I got a 0x7E STOP error.

It's hard to say what's happening in the class driver under the Partition Manager, but it looks like while attempting to mount the RAID device the Intel storage driver caused a bugcheck:

The USBSTOR stack running on CPU 0 is calling _ProcessNeoStateChangeList, which parses USB endpoints to find attached devices and as such requires elevation of IRQL to dispatch mode to parse for those potential endpoints. The iaStor stack of the loading of the iaStor driver (doing something, but not obvious what without symbols) has a dispatch IRQL and is in the process of releasing a SpinLock at the time of the bugcheck. I don't believe that the USB stack is in any way related, because in it's current state, it is waiting for this iaStor thread to finish - in essence, it is doing nothing but waiting.

Ultimately, both of these dumps seem to point to either the Intel driver, or whatever it's mounting. It looks like this is an Intel DX58SO board, and the latest RST driver for that board is the November 2010 release, according to Intel, which it looks like the install is already using. Short of a BIOS update to the May 2012 release, I'm not sure what else you could try short of removing the drives and trying with known good ones. It does look like either a driver or, more likely, drive or array problem.

Thanks for taking a look. It is indeed a DX58SO board, however it is a corporate sample. There are 2 RAID arrays involved besides the RAID5, the other is a RAID1 which holds the boot volume. It is difficult to determine which of these arrays could be causing the problem, other than the MBR read error that Gmer threw. In other testing, the OS will still BSOD when the boot array is degraded (booting with 1 drive). WD Tools flat out refused to test the disks, as it read them as being blank.

I had hoped some concrete evidence would show up in the dumps, but an upgrade may be in order. That may either be a total rebuild of the boot array, and/or upgrading the board. Hopefully it doesn't turn out to be caused by the data volume, but since Safe Mode is fairly stable, backing it up shouldn't be a problem.
