Description Jakub Ambrożewicz 2005-12-12 03:47:37 UTC 
Most recent kernel where this bug did not occur:
Distribution: Debian GNU/Linux Sarge
Hardware Environment: Acer TravelMate 2403NWXMi, bios ver.: 2.10
Software Environment: 
Problem Description: During boot with acpi enabled kernel hangs very early.
earlyprintk=vga shows the error
Kernel Panic: IOAPIC[1]: Unable to change apic_id!
When booting with "acpi=off" everything including touchpad works ok (except acpi
of course)
When booting with "acpi=noirq pci=noacpi,usepirqmask,routeirq" acpi works but
touchpad doesn't

Additional info (dmesg, dmidecode, acpidump, kernel config etc) are here

Steps to reproduce:
Boot kernel without acpi=off
Comment 1 Len Brown 2006-08-10 01:15:16 UTC 
Has any ACPI-enabled IOAPIC kernel ever booted on this system?
Still an issue with 2.6.17.stable?

Please verify that an ACPI kernel works fine if booted with "noapic"
Comment 2 Jakub Ambrożewicz 2006-08-19 03:04:54 UTC 
Yesterday i got access to that notebook again. It seems that 2.6.17.8 
works like a charm even with apic and ioapic enabled.
