Bad sched. while atom. when rmmod'ing ohci1394 ( Rev 1079 ) on2.6.0-test5-mm2 + latest svn checkout

[Philippe Gramoullé]

 Hello,

I was temporarily given an external (LA Cie) Fujitsu firewire hard drive (and below is the message i got while rmmoding the 
ohci1394 module ( 

Host is a Dell 530MT SMP running vanilla 2.6.0-test5-mm2 + latest ieee1394 svn checkout at the time of writing).

Sorry if this is a known issue that is being worked on but i haven't been able to follow ieee1394 development closely
in the recent weeks.

Let me know if you'd like me to try again with the latest linus/-mm tree

Thanks,

Philippe
