Re: ACPI problems on Athlon MP system

Hi Martin,

it seems that the ACPI support for APICs and/or IO-APICs is currently
not fully functional (at least in 2.4; don't know about 2.5). Many
people on this list, including me, need to disable APIC support in the
kernel or in the BIOS, if the BIOS setup has such an option, to get
their systems to boot.

And then, the IDE subsystem of 2.4.21 has changed a lot from 2.4.20,
and it could well be the case that 2.4.21-pre2 has still bugs that
raise their head on your system.

(On my MS-6533EG P4 SiS650 mainboard, the 2.4.21-pre2 IDE works much
better than the 2.4.18-2.4.20 kernels -- now I can finally burn DVDs
on my Pioneer DVR-105 with DMA enabled --  but your mileage may vary.
After all, 2.4.21-pre2 is still, well, "pre".)

Good luck,
Arndt
