Re: Linux 2.6.30-rc1 boot failure on ia64 w/ QLA12160. Bisected.

[Robin Holt <holt@sgi.com>]

On and ia64 system with a QLA12160 adapter, my boot fails with:

qla1280: QLA12160 found on PCI bus 0, dev 3
qla1280 0001:00:03.0: PCI INT A -> GSI 61 (level, low) -> IRQ 61

I did a git-bisect and narrowed it down to:

When I revert that commit from the 2.6.30-rc1 revision, I get a bootable
system.
