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"Master Abort" means the MMIO transaction timed out - usually due to the device not responding to an MMIO read.
LBA_CFG_RESTORE(). Are these okay?It seems probable that the problem that Carlo is having is a conflict between devices.
