This is kernel 3.9.9-302.fc19.x86_64. I plugged in a BN Nook (a usb mass storage device), used it, and ejected it. This makes suspend fail:

Experimenting a bit, here's what happens. - Plug in device (so it's working). Suspend works. - eject /dev/sdb. Suspend fails. - Physically unplug the device. Suspend works again. This is actually a real issue -- my laptop can continue to power its usb port while suspended, and the Nook is functional (and charges) while plugged in but ejected, but I can't suspend my laptop so it can charge my Nook. Curiously, this issue seems to be Nook-specific. I can't reproduce it with a Corsair Flash Voyager. --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
