Zitat aus linux/Documentation/kernel-parameters.txt
:
maxcpus= [SMP] Maximum number of processors that an SMP kernel
should make use of. maxcpus=n : n >= 0 limits the
kernel to using 'n' processors. n=0 is a special case,
it is equivalent to "nosmp", which also disables
the IO APIC.
nosmp [SMP] Tells an SMP kernel to act as a UP kernel,
and disable the IO APIC. legacy for "maxcpus=0".
Ja, diese lassen sich aber nicht debuggen, da die Kernel-Panik auf mehreren Prozessoren entstanden ist.
