[ And the same thing in ISO-8859-1 encoding... :-| ]

I caught two instances of the above BUG() in rmque() after [decoded oopses attached]. The kernel is 2.4.17, untainted but with a few patches (low-latency, o1, elevator, lkcd). I've got a full kernel crash dump from the second instance in case it is needed.

I'm currently running 2.4.18 and just the lkcd patch in order to see if the problem recurs.

MikaL

ksymoops 2.4.5 on i686 2.4.17o1-ll-elv-lkcd. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.17o1-ll-elv-lkcd/ (default) -m /boot/System.map-2.4.17o1-ll-elv-lkcd (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?
