One thing I've found when using grub2, then grub interprets the
semi-colon between multiple BDF triplets as a separator, e.g. in the
above case it
would only pass to the kernel
pci=resource_alignment=0e:04.0
and then give an error
error: unknown command `0e:04.1'
the fix is to wrap single quotes around the clause, e.g
module /boot/vmlinuz-2.6.32.12-0.7-xen root=/dev/cciss/c0d0p2
resume=/dev/cciss/c0d0p1 splash=silent showopts vga=0x317
pciback.permissive pciback.hide=(0e:04.0)(0e:04.1)
'pci=resource_alignment=0e:04.0;0e:04.1'
Hopefully google will squirrel this a way and it be useful to anyone
else hitting the same issue ...
