Problems with VIA Apollo Pro Chipsets

Problems with VIA Apollo Pro Chipsets

[Erich Schubert]

I have a system using the Gigabyte GA-6VTXDR-C Motherboard which showed
the VIA Southbridge symptoms with our 3ware Escalade RAID Controller.
On heavy load (such as kernel compilation) i get random segmentation
faults on different places, not reproduceable but every now and then.

I noticed that the quirk_vialatency was not enabled, and modified
quirks.c accordingly - but this did not yet solve the issues :-(

Any idea? (except handing the system back to the manufacturer and
asking for a working system...)

Note for this patch: in the line above my addition, 0x3112 has now an
according definition in include/linux/pci_ids.h, so this "Not out yet"
could be replaced with the Chipset name:
#define PCI_DEVICE_ID_VIA_8361          0x3112

diff NOT needed. Re: Problems with VIA Apollo Pro Chipsets

[Erich Schubert]

After removing one memory chip that was broken (at least memtest86 found
errors) i got rid of all errors, it seems.
So this diff is NOT needed...

The diff seemed to improve things, but i guess that was just luck...
Sorry for being too fast on that issue.

My current kernel, 2.4.19-pre7-jp10, reports the bridge now as
00:07.0 ISA bridge: VIA Technologies, Inc. VT82C686 [Apollo Super South]
(rev 40)

So it probably isn't the known-to-be-broken one...
