So, ata_piix fails to suspend/resume properly on your machine? > It should work. Can you describe how it fails? Well I keep seeing this: ata3.01: revalidation failed (errno=-2) ata3: failed to recover some devices, retrying in 5 secs ATA: abnormal status 0x7F on port 0x40DF ATA: abnormal status 0x7F on port 0x40DF ata3.01: configured for UDMA/133 but I am still on 2.6.20-rc6 ... so sorry if this is now fixed in .20.
