I have seen an interesting oops

This happened when i booted with delo from disk and
directly after the "BOOTP" message should have been coming
i got this oops. Previously i got the following messages
on the console.

eth0: Memory error, status fe83
eth0: DMA error
LANCE unopened after 100 ticks, csr0=0001.

I guess this has something to do with diskbooting as this doesnt
happen when booting from tftp/net ...

This is a decstation 5000/150 KN04 V2.1k diskbooted with delo 0.7

Kernel is a 2.4.0-test9 from current cvs as of 001021

BTW: I got another oops when trying to process this oops with ksymoops
which i did not capture :(

----- Forwarded message from root <root@repeat.rfc822.org> -----

ksymoops 2.3.4 on mips 2.4.0-test9.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test9/ (default)
     -m /boot/System.map-2.4.0-test9 (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.

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