Oops with 2.4.16-pre1 (nfs related)

[Patrick Mau <mau@oscar.prima.de>]

Hi all,

today I had the following oops which makes the machine hang.
Lots of processes where in D state and I had no keyboard so
I pushed the Big Button and rebooted.

The kernel runs without modules and uses ext3.
Hardware is an old AMD K6-2, 384MB RAM, IDE Disks
VIA chipset ... what else is important ?

Maybe the kernel is a bit old but I wanted to report it
anyways. The machine was/is very stable otherwise.

ksymoops 2.4.3 on i586 2.4.16-pre1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.16-pre1/ (default)
     -m /boot/System.map-2.4.16-1 (specified)

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
