Right now I can tell you from personal experience that the VIA VT82C686A
chipset is causing kernel deaths, corrupted data on my drives, and UDMA
issues (meaning that when I enable the UDMA support the kernel
CONSISTENTLY crashes.)
This is all pre patch-2.4.1-pre11. I've not tested the new patch as of yet
as I was in a car accident and have not felt well enough to mess with
things. I will however be testing the new patch in about a half hour. The
test bed will be the SMP box I've been talking about on the list, Red Hat
7.0 (only one that will install on the machine without dying instantly
during installation) and using the KGCC rather than the GCC that comes
with RH7.
Supposedly there are a couple of other patches available to add as well,
but I'm not sure where they are exactly. I just downloaded the patch that
Voj gave (v3.20) for the VIA chipsets.
Nicholas, give me a bit and I'll let you know what's going on with my
tests here. I can consistently get the current kernel to die simply by
running
dd if=/dev/hda4 of=/tmp/testing.img bs=1024M count=2k
TRy this on your box with the patch-2.4.1-pre11 added to the kernel source
and let me know what you get. Maybe we can work on this together.
