Note that ioremap doesn't get a virtual address, but a bus/phys one.
The virtual address checked in the BUG above comes internally
out of vmalloc's address space allocation.

The bug is more likely that either the kernel page tables or the
vmalloc vmlist are inconsistent somehow. In particularly it looks
like vmalloc gave out an address for ioremap on which there was
already a mapping.

I doubt it is qla2x00's fault.
