With a kernel built May 4 I got many hangups after leaving the machine run overnight. The screen auto-blanked before it locked up, so I couldn't determine what the cause could have been. I did hava a java app running, and that may have been the cause. Since then I've updated to 5.1 BETA (may 7) and removed atapicam, pass, cd, cbb, cardbus, and pccard from the kernel. No problems since, although the hard freeze persists when I insert a pc card into the machine when cbb is enabled. Will Saxon wrote: >Has anyone been experiencing non-panic hard freezes lately?

I am always suspicious of hard lockups, it is difficult to pinpoint what causes them since there is no log entry to read. It could easily be a hardware issue, but since I hadn't had problems before -current I thought I would write in. > >-Will >_______________________________________________ >freebsd-current@freebsd.org mailing list >http://lists.freebsd.org/mailman/listinfo/freebsd-current >To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" > > >
