Huh, the same problem, lockups with K6-2 500MHz but with
another S3 card.
I have changed only the CPU from K6-2 266 (overclocked to 300, running
stable for more than 2 years) with a K6-2 500MHz model 8 stepping 12.
The change occured in 2.2.18pre19 but I tried with different kernels:
2.2.18pre19 - plain, no MTRR support
2.2.17 - plain, no MTRR support
2.2.18pre22 - with 2.2.18pre21aa2 and ide patches, with MTRR support
2.4.0-test11 - plain, with MTRR support
When MTRR support is compiled in, I don't put any settings in /proc/mtrr
Sometimes the lockups are forever (I don't wait them for more
than 15mins => power off) or for 3-5 seconds, mouse stops, vmstat
shows 100% user CPU busy in these 3-5 seconds, 17 blocks written:

The CPU is cold. The problems occur when there is no big
CPU/disk activity. It can work without problems even when I make bzImage
or running benchmark software (nbench).
Tested on XFree 3.3.5 and 3.3.6: the same lockups. The lockups can occur
when I switch the virtual destktops from the KDE panel, when working
with the pine program or when starting new console terminal on the same
desktop. No problems in text consoles, only in KDE 1.1.2 and 2.0. Two
times I saw something strange: the video image was zoomed and showed
twice in the upper half of the screen. No lockups but switching to/from
text consoles solves the problem.
Tested with Windows 95/98, works on the same hardware with no
problems!!!
The hardware:
Video S3 GX2 4MB AGP, Motherboard: Shuttle 591P Via MVP3,
BIOS image 591pwiqf, 192MB RAM
Bus 1, device 0, function 0:
VGA compatible controller: S3 Inc. ViRGE/GX2 (rev 6).
Medium devsel. IRQ 10. Master Capable. Latency=64. Min Gnt=4.Max Lat=255.
Non-prefetchable 32 bit memory at 0xd0000000 [0xd0000000].
So, is this a S3 problem with many different cards or this is a
K6-2 stepping 12 problem, kernel K6 support or XFree problem?
