Hi Igno,

I have the same troubles with O3 at home on my SMP machine, however
since the same kernel (2.6.8-rc2-mm2-O3) works flawlessly here at work
on a UP P4 I thought it to be SMP related.

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
