The last messages that appear are: Disabling non-boot CPUs CPU0 attaching NULL sched-domain CPU1 attaching NULL sched-domain In the kernel bugzilla I found the following helpful entry: http://bugzilla.kernel.org/show_bug.cgi?id=11725 (clockevents: broadcast fixup possible waiters) So I did some tests: 2.6.24 ------ With rt20 the following two patches got added: 7300711e8c6824fcfbd42a126980ff50439d8dd0.patch 7300711e8c6824fcfbd42a126980ff50439d8dd0-fix.patch I removed both of them and my PCs are powering off again. 2.6.26 ------ With the stable kernel version 2.6.26.6 the following commit was added: clockevents: broadcast fixup possible waiters: 92741d2d653769b582015c6a379e7b46e113435d When I revert this commit my PCs are powering off again. 2.6.29 ------ 2.6.29-rc4-rt2 is ok! So my question is: Is it ok to remove the change "clockevents: broadcast fixup possible waiters" from the 2.6.24 and 2.6.26 kernel version? (From the commit comment "Until the C1E patches arrived..." I guess that it could be ok since the C1E patches were -as far as I can guess - added to the kernel after 2.6.26.) Best regards Matthias
