Re: 2.6.18-mm1

[Andy Whitcroft <apw@shadowen.org>]

Ok.  Now that we've got past the linker changes breaking down under
older tool chains I am getting following panic on boot.  The machine has
one of these, other machines do seem to boot:

0000:02:04.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030
PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07)

It appears that this driver is unchanged between 2.6.18 and -mm1.
2.6.18 boots just fine.  Odd.

Any suggestions?
