Joel it seems that you should be able to add "nohz=off" to the
kernel boot command line as a workaround for this bug.
I have rebuild the _same_ kernel with qla2xxx in module and
external firmware. I have checked that both module and firmware are in
my initrd. 2.6.30 hangs when it load qla2xxx module with "NMI watchdog
on CPU1" and "NMI watchdog on CPU0". If I retry with nohz=off option,
it boots.
For information, my initrd :

Is the problem I met on V240 could be related in some way with this :
http://marc.info/?l=linux-sparc&m=124092535426803&w=2
Same procs, different machine, NMI related too, so I wondered if it
could be some different symptom of the same problem.
