I have a machine with an Adaptec 2940U2W adapter running 2.6.11. When I try to go into standby like so: echo standby > /sys/power/state this is what happens: Stopping tasks: =============================================================== stopping tasks failed (1 tasks remaining) Restarting tasks...<6> Strange, ahc_dv_0 not stopped done The machine fails to suspend, and ahc_dv_0 is now wedged, consuming all available CPU until reboot.
