Subjectagain: ATM (LANE) - related Kernel-Crashes

... it happened again -
attached below is the output of ksymoops regarding a recent oops.
The machine is currently running Kernel 2.4.7 / atm-0.78.

In the past, I had had several crashes running different
kernel/atm-versions,. The machines are HP Netserver with a ForeRunner
LE ATM-NIC (hardware is checked and o.k.). The other network equipment
(ATM-, Ether-switches .. is also mostly by Fore Systems. The crashes
seem to occur always at night without any significant load on the
machine or the network. All the crashes occured in ATM/LANE code,
unfortunately on different places. Besides that, I personally can't
identify any particular pattern.

Maybe somebody with more insight into LANE has any idea, what is
going wrong ...

Is anybody else experiencing similar problems? The ATM-system is
labelled "experimental", is it generally that unstable? As far as I
can see, the MTBF seems to be about 2 weeks (unfortunately, I don't
have much alternatives ...)

ksymoops 2.4.0 on i686 2.4.7. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.7/ (default)
-m /boot/ (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?
