Random CPU initialization on Athlon SMP
Hello niteowl,
Quoted 4 lines
I have a very strange problem on my dual Athlon MP system since CPU initialization seems to be performed in a random way. In about 50% of bootstraps the kernel manages to correctly enable the second CPU, in the other 50% not.
I have the same problem with almost the same configuration ...
I think it's not an hardware problem, if you find a solution let me know asap I'm looking for info and similar problem report but until now i found nothing useful.
Good luck!!

I found that passing the "acpismp=force" option to the kernel the problem is much less frequent. I don't know why, neither I know what this option precisely does.
I think that the problem is in someway related to ACPI or to something that is indirectly involved by ACPI.
