2.6.12-git1 broken on x86_64 (works on 2.6.12)

[Martin J. Bligh]

Fails to reboot, see:

http://ftp.kernel.org/pub/linux/kernel/people/mbligh/abat/6035/debug/console.log

basically:

VFS: Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Looks like it didn't find the SCSI card at all ... MPT fusion, IIRC.
I'll poke at it a bit tommorow, but if you've got any good guesses as
to what broke it, let me know (hopefully something trivial like config
options).

Whatever driver serves sda1 does not seem to get started at all.
So probably config breakage.

If ABAT copies an older .config with CONFIG_FUSION=y, the new config
disables it since it now has two different options CONFIG_FUSION_SPI
and CONFIG_FUSION_FC. Try manually setting those two new fusion options.

I had to do this in 2.6.12-mm1.

Thanks

Yay, that fixed it. Awesome - thanks ;-)
