Since today, I can't boot the 2.4.5 SMP kernel any more. I get a kernel panic (invalid page request at 0000000000000010) after SMP is enabled (actually the last message I see is "trying to unmount old root ...", but from kdb messages and the fact that uniprocessor 2.4.5 boots, it is clear that it is a SMP error). The panic happens before syslog startup, so I can't send a backtrace right now (I do not have a serial console ready). kdb backtace leaves me in the start_ap function. My BIOS has reported "8140 Processor in socket M0 failed FRB level 3 timer" for some time, but that didn't cause problems before and still doesn't with 2.4.4. Any ideas?
