Dual G5 XServe + Fibre Channel panics

[peter.g.harper at magnox.co.uk]

I was happily running G5 Xserves with Fibre Channel cards connected to a
RAID using 4.0
(kernel 2.6.8) and changed to use the 2.6.10 kernel to overcome a problem
with NFS.

2.6.10 sorted the NFS problem but when I rebuilt the kernel to enable Fibre
Channel support
I cound not get it to boot. I had the same problem with 2.6.9. I think that
it is a problem with
2.6.10 rather than a ppc problem.

There is a bug report

The bug number on bugzilla is 4077 and is dated 22nd January 2005

Perhaps you could try using a 2.6.8 kernel, the one that comes with YDL 4.0

I am getting a fun signal 11 error again when I try to load my fibre
channel module. This time I swapped out the Apple-OEM LSI card, and put in
a Qlogic ISP2312. I am using the qla2300 drivers from qlogic. (Also tried
the ones built into 2.6.10-1.ydl, same error as below.

Driver version qla2xxx-8.00.03
Kernel version 2.6.10-1.ydl.1custom - I added in a few more drivers I
needed. It is directly based off of the '2.6.10-1.ydl.1g5-smp'
configuration.

I have a feeling I may be missing some configuration step perhaps. If
someone has these working in 2.6.10, could you please send me your kernel
config file? Or if this is a non-ppc issue and I should take it to the
scsi lists, let me know. :)

Thanks,

Randy

Below is the output when I try to load the kernel modules.
