Description Tilo Lutz 2006-02-19 17:31:26 UTC

Hi

Many Acer notebooks have broken bios and report a 2nd apic
controller. This causes the kernel to crash.
Unfortunatly apic is required to get most hardware to work.

I found a patch here:
http://www.ussg.iu.edu/hypermail/linux/kernel/0502.1/1450.html
It still works with the current 2.6.16 kernel.

I opened an kernel bug:
http://bugzilla.kernel.org/show_bug.cgi?id=4700
Unfortunatly they need very long to add this patch.

It would be great if tis patch will be included in the suse kernel.

At the moment yast is crashing during installation when apic
is not enabled.
modprobe hangs during loading sounddrivers.

I use an Acer Travelmate 3000

By the way: Suspend of Ram is working out of the box with beta3 :)

The patch looks safe for me and continuing with a warning instead of panic in this case should be the better choice.
Len, what do you think about it ?

Yes patch looks reasonable, but it would be better if it was in mainline
first. 

Len doesn't actually maintain that part I would say, unfortunately
there is no dedicated i386 maintainer.

kernel.org bugzilla is not the right way to submit kernel patches for
mainline. Send it to linux-kernel@vger.kernel.org cc: akpm@osdl.org for this
case. Feel free to cc me.

Comment 3 Andreas Kleen 2006-02-28 14:31:46 UTC

I submitted the fix to mainline and we got it back from there now.
