SMP-machine hangs at the APIC message during the boot process

Support knowledgebase (apic_error)
Applies to

SuSE Linux: Versions since 7.1

Symptom

The installation or the boot process hangs at the message APIC error interrupt on CPU#0, should never happen. ... APIC ESR0: 00000002 or unlisted/blacklisted board, DISABLING IO-APIC IRQs'

Cause

The first error message means that there´s an hardware error, the second error messages means that the usage of APIC doesn´t work.

Solution

During the installation:
Type in linux noapic and/or reboot=bios at the boot prompt:
boot:linux noapic reboot=bios

For booting up (not necessary, if you´ve already specified "noapic" during the installation):
Run YaST1 and choose "System administration" -> "Kernel- and boot configuration" -> "Configure LILO". Please type noapic into the append line.

Or: Edit the file /etc/lilo.conf and add noapic to the append line.

In both cases please note, that the options have to be separated by a blank space. Example:

append="BOOT_FILE=/boot/vmlinuz_24 noapic"
