I also tried booting my dual athlon with noapic but that did not solve the problem. I have not had enough time yet to file a proper bug report but seeing this message I wanted to second it. Are there any known SMP related problems with your patches? and would my dmesg and .config from home be enough ? kind regards, Peter Zijlstra
