I'm having plenty of this on boot, on my SMP/HT desktop (P4/x86), while
running RT-V0.7.44-01 (SMP+PREEMPT_RT):

BUG: kstopmachine:xxxx RT task yield()-ing!

See sample dmesg and .config on attach.

OTOH, on my laptop (P4/UP), all seems to be clear fine.

Is this something to be affraid of? :)

Cheers.
