I've tried a number of things but can't tell what's going on. It never happens w/ ahci and reportedly sata_mv which can issue NCQ commands to multiple devices simultaneously like sil24 does. Disable NCQ for devices behind 4140 PMP for the time being. Signed-off-by: Tejun Heo Cc: Mark Lord Signed-off-by: Jeff Garzik --- Reading git-diff-tree failed
