This document (7003498) is provided subject to the disclaimer at the end of this document.
Environment
SUSE Linux Enterprise Server 11
Situation
x86 architecture (32 bit) only
When booting a 32 bit kernel on an AMD system with 8 cores or more in a CPU package (e.g. during installation), the boot process stopps with the following error message:
Error: Kernel panic - not syncing: Boot APIC ID in local APIC unexpected (16 vs 0)
The x86_64 version of SLES 11 is not affected by this problem.

Error: Kernel panic - not syncing: Boot APIC ID in local APIC unexpected (16 vs 0)
The x86_64 version of SLES 11 is not affected by this problem.
Resolution
The problem can be solved by adding apic=bigsmp as a boot parameter.
Additional Information
If other APIC related symptoms on SLES11 x86 systems (systems with a lot of cores) are experienced, it would be also worth trying the above boot parameter.
The error might be fixed in a future Service Pack.
