I had similar trouble with 2.6.20.1 (running UP on a 200 MHz Pentium MMX machine) when I unloaded the nf_conntrack_h323 kernel module. The messages continued until I rebooted, although I never saw an oops. I am currently avoiding the problem by *not* unloading any netfilter modules. Cheers, Chris ___ All new Yahoo!

kernel BUG at mm/slab.c:610
Hello everybody. Sorry for posting to this list, but I'm pretty lost. I'm experimenting this kernel panic on 3 different slackware linux boxes. The harware is the same, and also the .config with vanilla 2.6.20 I don't think this is related to buggy hardware because it is happening on 3 different boxes with the same hardware config. Unfortunately the bug isn't reproducible but it is happening at least once a week. May anoybody point me the step to try to spot this bug? TIA ksymoops 2.4.10 on i686 2.6.20. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.6.20/ (default) -m /usr/src/linux/System.map (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.

kernel BUG at mm/slab.c:610
Hello everybody. Sorry for posting to this list, but I'm pretty lost. I'm experimenting this kernel panic on 3 different slackware linux boxes. The harware is the same, and also the .config with vanilla 2.6.20 I don't think this is related to buggy hardware because it is happening on 3 different boxes with the same hardware config. Unfortunately the bug isn't reproducible but it is happening at least once a week. May anoybody point me the step to try to spot this bug? TIA ksymoops 2.4.10 on i686 2.6.20. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.6.20/ (default) -m /usr/src/linux/System.map (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.

Some program might be trying access hardware directly. That sounds familiar... I had similar trouble with 2.6.20.1 (running UP on a 200 MHz Pentium MMX machine) when I unloaded the nf_conntrack_h323 kernel module. The messages continued until I rebooted, although I never saw an oops. I am currently avoiding the problem by *not* unloading any netfilter modules. Cheers, Chris ___ All new Yahoo!
