Subject: atyfb & lockups
Date: Wed, 30 Nov 2005 16:51:44 +1100 [thread overview]
Message-ID: <1133329905.16726.69.camel@gaston> (raw)
I have an old PowerBook Wallstreet I here with a Rage LT-G. I've been
booting it from Open Firmware instead of MacOS lately (thus didn't give
a chance to the MacOS driver to do it's own tweaking of the chip) and
the machine has been reliably locking up on me. Solid lockups. I finally
figured out that the lockups appear to be atyfb related and that booting
with video=atyfb:noaccel fixes it.
It seems that when it's lockup, the whole machine is down, that is it
won't take interrupts to get to the xmon low level debugger nor
anything, thus I suspect the PCI is locked up.
Are there any ideas of where to look for the source of the problem ?
Ben.
