Subject: VIA KT133A crash *post* 2.4.3-ac6
Date: Tue, 12 Jun 2001 13:10:55 +0100	[thread overview]
Message-ID: <> (raw)

This seems to just run and run... Sorry I couldn't report this earlier, 
but I've only just got this machine...

With DMA (UDMA Mode 5) enabled, my machine crashes on kernel versions 
from 2.4.3-ac7 onwards up to 2.4.5 right up to 2.4.5-ac13. 2.4.3 vanilla 
and 2.4.3-ac6 are completely stable. -ac7 of course is when a load of 
VIA fixes were done. :-}


System is:

CPU: Athlon 1.33 GHz with 266MHz FSB
Mobo: Asus A7V133 with 266MHz FSB, UltraDMA100 (PDC20265 according to 
kernel boot messages)
    BIOS has been updated to latest available (massively unstable before)
512Mb PC133 RAM
Voodoo 3
3Com 3C905B
IBM UDMA100 41Gb Deskstar


SuSE 7.1 updated to current-everything
SuSE default kernel and self-built kernels of various versions


With DMA disabled, *all* kernels are completely stable.

With DMA (any setting, but UDMA mode 5 preferred of course) enabled, on 
kernels 2.4.3-ac7 and onwards, random lockup on disk access within first 
few minutes of use - sometimes very quickly after boot, sometimes as 
much as ten minutes later given use. Running bonnie -s 1024 once or 
twice after boot generally excites it too. :-}. Lockup is pretty severe: 
machine goes completely unresponsive, Magic SysRq doesn't work. About 
the only thing that does still work is the flashing VGA cursor. :-)

Actual tested kernels:

2.4.0.SuSE, 2.4.0 vanilla, 2.4.3 vanilla, 2.4.3-ac6 - No failure
2.4.3-ac7, 2.4.4 vanilla, 2.4.5 vanilla, 2.4.5-ac13 - Failure.
