--- Comment #30 from Hin-Tak Leung htl10@users.sourceforge.net --- Have another hard lock up under 10.4.3/10.4.4. Just using mplayer and not running firefox - it was right before a scheduled reboot to upgrade to 10.4.4 so the system have 10.4.4 but 10.4.3 was probably cached - so that's probably not a good idea.
So that's 10 days since last crash.
