"Master Abort" means the MMIO

In lba_pci.c and sba_iommu.c, it says "BE WARNED: register writes are
posted" and need
to be followed by a read. It seems there are a some routines in these
modules that have
writes that aren't followed by a read. One is lba_wr_cfg(). Another
might be the macro
LBA_CFG_RESTORE(). Are these okay?
It seems probable that the problem that Carlo is having is a conflict
between devices.
