Same here - doing a dmesg in an xterm makes the machine hang for about
10 seconds and latencytop whinges that a raw SCSI command took 4000ms to
complete (uniprocessor x86 EeePC 900).
Additionally, you won't see this problem if you have CONFIG_PREEMPT set
but as my config has CONFIG_PREEMPT_VOLUNTARY=y I do see this problem.
Reverting f23eb2b2b28547fc70df82dd5049eb39bec5ba12 fixed the problem for
me too.
