My system periodically hangs, sometimes there are disk corruption after reboot.
While running I was comparing number of identical files between harddrive and CD copies. Comparison fails randomly (~one out of 100 files of 560MB worth of files).
Once file gets in cache it always fails if repeatedly compared. When it gets out of cache -- some other will fail. Sometimes bad copy is in CD, sometimes in HD. Once it gets out of cache -- doesn't fail again, but some other one will.
Differences in files that I've spotted: from 1 to ~32 bytes continuously.
What's unusual about my system:
* I have SATA RAID disk array (2 identical disks Maxtor 6Y120M0/YAR51HW0, mirrored) (became supported only in 5.3 ?)
* I run i386 on AMD64
* I have recent NVidia card, but problem happens even w/out drivers installed.
Difference in copy of file coming from CD to my mind is telling that it's not HD hardware.
And it's not memory: I've ran each of two 512MB memory cards separately -- happens on both of them.
Looks like someone in kernel does a bad write in the memory.
I know this is a tough one
but I am lost with this problem.
