Actually it is implemented in the aic7xxx driver, see ahc_suspend and ahc_resume. I tried it with 2.6.12, and I no longer have the problem with the ahc_dv thread as it no longer exists (AFAICT the functionality is handled by the SCSI midlayer now?). Now it just immediately resumes: [4297399.286000] PM: Preparing system for standby sleep [4297399.609000] Stopping tasks: ================================| [4297399.610000] Restarting tasks... done How can I debug this further?
