Linux 2.4.22-pre2 and AthlonMP

[Edward Tandi]

On the Tyan Tiger board (2460) fitted with two processors, if I use
'noapic' in the lilo boot options I get the following in messages (and
eventually a crash):

The system boots, but hangs shortly thereafter. Removing the noapic
option, I get the following new messages:

using option 'pci=noacpi' or even 'acpi=off'
Jun 28 18:27:46 machine kernel: BIOS failed to enable PCI standards
compliance, fixing this error.

I presume this last set of messages is due to the recent ACPI changes.
If I try booting with the suggested 'pci=noacpi', the machine hangs
during boot before it gets to the SCSI driver. Setting 'acpi=off' gets
rid of the messages and the box appears to run OK.
