SubjectFile System Corruption with 2.2.18
I am having all sorts of nasty file corruption problems with 2.2.18
patched with
ide.2.2.18.1221.patch.gz
linux-2.2.18-reiserfs-3.5.29-patch.gz
raid-2.2.18-B0

The corruption is occuring on my WDC AC28400R(I also had a problem with
a 13GB WDC as well which I swapped out last night). This is the only
hard drive that is on the onboard controller which is a VIA Technologies
VT 82C586 Apollo IDE (rev 6) chipset. The drive does share the IDE bus
with a internal ATAPI Zip drive. The cable I am using to connect the WDC
is a UDMA66 40pin 80 wire cable. I realize I do not have a UDMA66
controller, or disk, but I was having problems installing with a
standard 40 pin, 40 wire cable that the 80 wire seemed to alleviate.

The other drives are my software RAID setup on 2 Promise PDC20262
controllers with 1 drive per interface for a total of 4 drives. These
drives are Quantum 13X(?) 13GB drives. I am running the default RH6.2
kernel right now for stability with no support for my promise
controllers and I am writing this from a remote site so not sure of
other distinguishing marks of the quantum HD's.

So my question is does anyone have any idea what might cause ide dma
errors to occur when I use this kernel? As I mentioned file corruption
seems to only occur on the WDC drive(s) and manisfest itself as
executables suddenly becoming unreadable binary files, strange file
permissions on new files, and X windows going completely nuts when it
tries to start. I reboot back to the stock 2.2.14 with RH and everything
seems to work fine, excepting that I cannot access my RAID device of
course. :)

I have had this problem across two mother boards(both VIA chipsets), two
CPU's, two WDC Hard drives and the cable swap. I have not swapped RAM.

Thanks for any assistance/suggestions that you might be able to render.

Terrence Martin
