Some new problems with 2.4.5

[Vasil Kolev]

(I'm resending this, it looks like it was lost somewhere ... and there is
some more mem info...)

  Hello,

 I have a machine that's dual coppermine/927 (that's what /proc/cpuinfo say:) ), with 1.2G ram,
Dell PercRaid, 3com 3c905B NIC. I'm using kernel 2.4.5 with the percraid patches.
The problem with the machine is, that it works for some time, and then it goes to hell. I spoke
with Rik van Riel last night, and he asked me to get some info from /proc/meminfo around the
crash. I've appended it here, and the kernel log messages ( recovered from remote logging station,
the machine was unsuble and was rebooted through the power switch :) ) .
It doesn't look like the other problems reported with 2.4 VM, so I still haven't tried to use 2.4.6pre3,
because it's production machine, and I'd like to stuck with something that's not prerelease :)
( full log is avialable at http://www.ludost.net/eru/ - meminfo.log.bz2, the kernel log from the 'crash'
moment, and the dmesg of the machine).
(the log was created with while /bin/true; cat /proc/meminfo >> dumpfile;sleep 20; done ).
