Well, the real problem seems to be in touching link power management policy (it did not happen with ata_piix driver thus the driver seemed to be ok) If I touch power management with theses commands: echo max_performance > /sys/class/scsi_host/host0/link_power_management_policy echo medium_power > /sys/class/scsi_host/host0/link_power_management_policy the suspend fails. I always restore max_performance policy before the suspend. -- Luk??
