Re: [PATCH 2/3] libata: Add firmware_default LPM policy

Ok, I've had one person testing this report the following:

[ 1896.902726] ata1.00: exception Emask 0x0 SAct 0x800 SErr 0x40000 action 0x0
[ 1896.902735] ata1.00: irq_stat 0x40000008

[ 1896.942783] ata1.00: configured for UDMA/133
[ 1896.942815] ata1: EH complete

which seems to occur in batches. I'm a little confused - isn't it
legitimate for the phy to report comwake here?
