Hello, Disabling sd_resume() gives me a "quick" resume again (few seconds), though it doesn't get rid of the COMRESET errors: [ 2.476417] ata1: device not ready (errno=-19), forcing hardreset [ 2.476440] ata2: SATA link down (SStatus 0 SControl 310) [ 2.824896] usb_endpoint usbdev2.3_ep00: PM: resume from 0, parent 2-1 still 2 [ 2.824902] usb 2-1:1.0: PM: resume from 2, parent 2-1 still 2 [ 2.824906] usb 2-1:1.1: PM: resume from 2, parent 2-1 still 2 [ 2.824910] usb 2-1:1.2: PM: resume from 2, parent 2-1 still 2 [ 2.824914] usb_endpoint usbdev2.3_ep05: PM: resume from 0, parent 2-1:1.2 still 2 [ 2.824919] usb_endpoint usbdev2.3_ep85: PM: resume from 0, parent 2-1:1.2 still 2 [ 2.824923] usb_endpoint usbdev2.3_ep81: PM: resume from 0, parent 2-1:1.0 still 2 [ 2.825392] Restarting tasks ... done.

Is it really needed to do polling? Idea: What about implementing a sata_sil specific .check_status function, instead of using the generic ata_check_status()? That one could check other registers to find out what's really going on in the case ENODEV is returned by ata_check_status(), or something like that.
