I've got a Dell Precision 420 (dual P3/800 w/1gb RDRAM).
I'm consistently getting an oops when accessing any smbfs mount whether
running 'ls' inside the smbfs mount or hitting TAB for filename
completion of a directory in an smbfs mount. I have another machine
(dual P2/300 w/320MB memory) that does not have this problem. The P2
has an eepro100 ethernet card whereas the Dell has the built-in 3c920
(3c905c emulation).
Below is the ksymoops output. The oops screen I manually typed onto my
other computer because the /var/log/messages file gets corrupted when
this occurs and I don't know how to save the oops screen on the computer
itself. SAR-S, SAR-U say they're doing to do their action but do not
actually sync or remount the disks. CAD does not reboot the computer.
SAR-B does reboot the machine though.

Ethernet is compiled into the kernel as is smbfs (not as modules). I've
compiled this kernel with 4GB bigmem support (otherwise I only get 8xxMB
total).
If anyone needs more please let me know.
