| |
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
