Yeah, thanks Maurice, I just saw that one this afternoon. I guess you can''t reboot with iscsi full stop... o_0 And I''ve seen the iscsi bug before (I was just too lazy to look it up lol), I''ve been complaining about that since February. In fact it''s been a bad week for iscsi here, I''ve managed to crash the iscsi client twice in the last couple of days too (full kernel dump crashes), so I''ll be filing a bug report on that tomorrow morning when I get back to the office.
