Reply: Steven Walter: "Re: VIA text console corruption and fix."

The VIA bug-fix that got added in 2.4.18 still has issues. I've
included as good a bug report as I can, and a patch that "works for me".

[1.] One line summary of the problem:

The text console gets corrupted on some VIA motherboards in 2.4.18

[2.] Full description of the problem/report:

When booting kernel 2.4.18, before /sbin/init is run, the text console
becomes corrupted and unreadable. Vertical lines appear on the screen
in a multitude of colours. The X server will still start, and run as
normal. You can login over ssh.

[3.] Keywords (i.e., modules, networking, kernel):

kernel, console, VIA

[4.] Kernel version (from /proc/version):

2.4.18-pre1 and later. Absent in 2.4.17 and earlier.

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

N/A

[6.] A small shell script or example program which triggers the
problem (if possible)

Just boot.

[7.] Environment

I have 3000+ identical VIA KT133/Duron 750MHz machines. In 20% of these
the bug is visible, in the others, it isn't. The machines run in an
LTSP-ish configuration. The machines are supposed to be identical (they
were bought together), but have different revisions of BIOS versions,
etc. They have on-board S3 Savage cards that steal RAM from the main
RAM.

[7.6.] SCSI information (from /proc/scsi/scsi)

N/A

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):

At the end, I've included /proc/cpuinfo, /proc/ioports, /proc/iomem, and
lspci from a machine that is supposedly identical, but doesn't have the
bug. I've been playing with BIOS settings (enabling/disabling USB,
Audio, etc.), but I think I have them similar again. There are some
differences: different IRQs.

[X.] Other notes, patches, fixes, workarounds:

The following patch fixes it for me:
