Hardware:

MSI K7T Turbo R
Athlon Thunderbird 900MHz (not overclocked)
256MB PC133 SDRAM
Soundblaster Live!

Kernel is 2.4.8 with two patches - Rui Sosa's emu10k1 compile patch and the
linux-2.4.4-openssl-0.9.6a-mppe.patch from
ftp://mirror.binarix.com/ppp-mppe (for encrypted PPTP connections) built
with Athlon optimizations (.config file is attached).

History - kernel 2.4.6 (with CVS emu10k1 driver and the MPPE patch) runs
rock-solid on this machine. Since I upgraded to 2.4.7 (again with CVS
emu10k1 and the MPPE patch) I started seeing hangs. At that point I could
not get oops information, unfortunately. Today I installed 2.4.8
(configured as above) and started getting hangs again. I then set up serial
console and managed to get an Oops. While I was running that Oops through
ksymoops I got another Oops! Following are both Oops:

First Oops:
------------------------------------------------------
ksymoops 2.4.0 on i686 2.4.8. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.8/ (default)
     -m /boot/System.map-2.4.8 (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
