Dominik, could you try it and send us the new kernel logs whenever > you happen to hit that warning message again? (Please also enable > CONFIG_KALLSYMS_ALL, so that we get as much symbolic data as possible.) I tried to compile the patch on top of 2.6.13-rc4-mm1, it applied with a few offsets, but it looked ok. Here is the error I get when I compiled it: CC arch/x86_64/kernel/traps.o arch/x86_64/kernel/traps.c: In function `show_trace': arch/x86_64/kernel/traps.c:228: warning: implicit declaration of function `print_traces' arch/x86_64/kernel/traps.c:228: error: `task' undeclared (first use in this function) arch/x86_64/kernel/traps.c:228: error: (Each undeclared identifier is reported only once arch/x86_64/kernel/traps.c:228: error: for each function it appears in.) make[1]: *** [arch/x86_64/kernel/traps.o] Error 1 I took a look at the traps.c file, but couldn't find any solution, as there is no print_traces function and task variable too in this section. dominik
