I have the same issue as Adam Wight reports but on completely different hardware. I suppose it could be an issue with the Intel driver?
The issue occurs randomly while using the computer, minutes to several hours after booting the system will freeze, leaving only the mouse cursor working until that too freezes after a few more seconds. Sometimes it will become responsive again after a minute or so only to hang again shortly thereafter.
Looking in Process Explorer during a freeze the System process (PID 4) is using 25% CPU (this being a quad-core system) and the thread with start address "iaStor.sys+0x213d4" is using all of it.
No error messages in event log that I can recognize as being relevant to the issue. My RAID (I have six disks connected to the ICH9R controller) appears to be working fine (I have done both extensive reading and writing over the last few days with no issues.) No warnings or errors in device manager.
As this problem did not occur for me previously it may well be related to the new version of the Intel RST driver that I recently installed (10.1.0.1008). I could try and revert to a previous version to see if that helps.
CPU: Intel Core2 Quad Q9650
Motherboard: Asus P5E64 WS Evolution (Intel X48 chipset)
Memory: Corsair XMS3 DHX DDR-1066 (4 x 2 GB)
Graphics: ATI Radeon HD4870X2
Sound: Creative SoundBlaster X-Fi Fatal1ty
Disks (on Intel ICH9R): 2x WD3000-HLFS-01G6U0 (RAID1), 4x Seagate ST3320620AS (RAID5)
Other (on Marvell controller): Samsung DVD-ROM reader, NEC ND-1300A writer, external WD WD10EADS-00L5B1
As you can tell, a setup quite different from Adam's, so I doubt that this is something as simple as a hardware conflict. Otherwise I would have seen the issue sooner! I have not made any hardware changes in a year, yet this issue has been happening only recently!
Thanks for any assistance you might offer!
There, now I've registered as well.
Adam, it would help if you could verify that you are also using the 10.1.0.1008 driver. It seems to be quite a recent release (12/15/2010) so if the driver is indeed faulty then if would only be affecting those of us with recent builds, or who regularly check for driver updates.
Before I had this issue I was using the older Matrix Storage Manager driver (version 8.9?) which did not exhibit this issue. I will try, hopefully this evening, to downgrade to an earlier Rapid Storage Technology driver - I believe the next previous release is 188.8.131.524 - to see if that resolves the issue.
since I suspect this to be a driver bug I filed an issue with Intel support. I got a reply suggesting I downgrade to 9.6:
I understand your computer is randomly freezing after installing new Intel® Rapid Storage Technology.
Unfortunately, this department does not have reports about this issue. At this point I would recommend uninstalling the latest Intel® Rapid Storage Technology and installing an earlier version 9.6. and if possible provide feedback
This software is available here:
I will try this tonight and I would suggest you try the same, if this ends up resolving both our problems then it is almost certainly a driver issue.
Okay, I downgraded the driver. Have been using the computer for about 3h30m now with no issues, a bit early to be waving the flag but based on previous experience I should have seen at least one freeze by now.
This is what I did:
- Checked the version of the Intel storage driver - confirmed to be 10.1.0.1008 (2010-11-06)
- Using Programs and Features, uninstalled Intel Rapid Storage Technology
- Installed iata96enu.exe (downloaded from link in previous msg)
- Checked the version of the Intel storage driver again - now is 184.108.40.2064 (2010-03-03)
On installing iata96enu.exe there is a warning about overwriting a newer driver. Just accept it. Also, uninstallning Intel RST from Programs and Features does NOT remove the driver, just the application and services. This is of course exactly what I wanted as I wouldn't be able to boot without the driver...
Adam, it would be interesting if you could try this as well and report your results.
I haven't downgraded the driver yet, but I did find a different solution that seems to be working. I had a RAID 1 array from my old system that I moved over into the DH67CL. Only one of the drives was found (I attributed the "missing" drive to a power or SATA cable not being plugged in all the way). Since I was going to be moving the contents of that array over to a larger array anyway, I didn't worry about it. I've had degraded RAID 1 arrays in the past that never impacted system stability. But after figuring out that it was the storage driver hanging the system process, I decided to go in and have RST delete the old array (I'd already moved all the contents to the new RAID 1).
Anyway, after deleting the old RAID array so that RST no longer sees a degraded array, I haven't had any more system hangs. Still seems like something must be broken in the driver (since a degraded array should NOT cause the system to hang), but as my system is now functional, I'm going to go with the "if it ain't broke, don't fix it" principle until a new problem pops up.
