I have a process to create tape boot images by combining the kernel and initrd into a zImage. The process works for 2.4 (RHEL 3.3) & 2.6 kernels (SLES9 & RHEL4). However on SLES8 ppc64 the kernel panics with "error kernel access of bad area pc". Anyone have an idea what is causing the failure? The error message appears to be pretty generic.
The exception is a "TRAP: 0600" which is an alignment interrupt. the trap occurred at NIP: C000000000085874 Get an objdump of your kernel, (or drop into xmon/kdb and use the disassembler commands) and see what instruction lives at that NIP address, and which registers it is referencing. (Then its a matter of finding out why the registers have bad data in them). (You probally have already done this, but if not... ) If you're booting off of tape in this instance, may want to try booting off of disk, and doing some tape operations after successful boot, to ensure the driver is all OK. -Will
