Description Mark Roach 2004-01-30 19:53:50 UTC 
Distribution:
Debian

Hardware Environment:
HP/Compaq nx9005
AMD XP2200+

Software Environment:
Problem Description:

Steps to reproduce:
ACPI is working fine with kernel 2.4.22 and ACPI patch 20030813, but boot hangs
with 2.6.0 and ACPI 20040116. Adding acpi=off to my boot parameters gets me in
fine, but obviously, no acpi.

Will post acpi info, it's from kernel 2.4.22 though.

Thanks

This appears to be my own fault, either the boot param to disable apic has
changed  or apic just has to be completely absent from the kernel for me to be
able to boot. Have successfully used 2.6.2 with apic left out. Sorry for the noise.
Comment 7 Len Brown 2004-02-05 01:18:32 UTC 
"noapic" will disable the io-apic (though it appears your box has none)
"nolapic" will disable the local apic
Note that there have been policy changes in the kernel which decide
whether to enable a lapic that the BIOS had left disabled.
There was also a 2.6.2 post rc3 apic.c fix based on the patch
in bug 1269 that fixes several boot hangs -- so you might try 2.6.2 with
the local apic enabled and/or the patch in that bug report.

cheers,
