I am trying to determine if our ATA/VIA setup code may have issues. I
did a google search and came up with a linux-quirks patch which may
apply to the random corruption problems people have been reporting.
Here is the URL:
http://www.linuxhq.com/kernel/v2.4/patch/patch-2.4.8/linux/drivers/pci/quirks.c.html
My question is: Does any of this apply to our ATA driver code? The
problem they are solving looks fairly serious.
I would also like to know if there is any sort of generic 'safe' pci
configuration that we can set for thet ATA driver to try to rule-in
or rule-out the driver as the cause of the memory corruption.
So far nearly everyone reporting these weird panics is running under
heavy IDE drive loads. I've received about 5 kernel core's from one
person and a core from another and investigated them. The corruption
appears to occur 'out of the blue', during heavy IDE drive loads.
There are no warnings or errors in the dmesg output prior to the
crash. I do not believe the kernel code itself is causing the
memory corruption.
The corruption appears to occur both for DMA and PIO modes. The
corruption does not appear to be a memory fault and I find it highly
unlikely that it would be a power supply issue. The people reporting
the problem have different video and ethernet setups. The only
common denominator (for at least 6 out of 7 of the people reporting
problems) is the fact that they are doing heavy IDE I/O and may also
be doing heavy network I/O (i.e. samba, NFS, etc....).
