so I'm still having serious stability problems with 2.2.6-Stable. My
last message was not very information-packed, but I'll do better this
time. One suggestion I had was to rebuild my linux LKM (as the
problem happened 100% when running linux stuff)... I've done this, and
it has not helped.
sources are spanking new 2.2.6-stable. World was last made, um,
may 11. M/B is an ASUS with BX chipset. RAM is SDRAM, non-parity.
Disks are seagate cheetah and an old 1 GB conner from a sun.
Here's my dmesg:

Crashes occur 100% instantly when running any linux programs. I
enabled the kernel debugger and so on. here's what i get (copied by
hand, of course):
fatal trap 12: page fault while in kernel mode
fault virtual addr: 0xb56d3104
fault code: supervisor read, page not present
instruction pointer: 0x8:0xf66d1a53
stack ptr: 0x10:0xefbffd8c
frame ptr: (same)
code seg: base 0x0, limit 0xffffff, type 0x1b, DPL 0, pres 1, def (no
idea what i wrote here), gran 1
proc eflags: interrupt enabled, resume, IOPL=0
current proc: 251 (sh)
mt mask:
the trace didn't seem to useful to me, so i didn't bother to include
all the addresses: (i'm doing something wrong, right?)
_end()
_execv()
_syscall()
_Xsyscall()
---syscall()
I do NOT think this panic only happens when running linux code, but it
is possible. (others use my machine, so perhaps at other times they
were running some linux whatever, not me.)
One thing that has changed with the machine is the ethernet card. I
had an intel card (100+) go belly-up a couple of days ago and replaced
it with the ZNYX which was kicking around. (the intel card got
*really* slow over the course of a couple of days, dropping down to
ftp transfers of 3kB/sec... replacing it with the ZNYX made the
problem go away immediately...) just tried replacing the intel
ethernet and the problem still exists, so i don't think this is
pertinant.
I have a 128MB core file with debugging symbols. Tell me what you
want me to do with it...
