I did not dig into kernel bisection yet. I've first restored an old Backup of January 2012 of Ubuntu 11.04 with kernel 2.6.38-13-generic. I was astonished that the hdd also is NOT mounted with this os version. As the HDD case now is also plugged directly into the mainboard's rear USB3.0 slot, instead of using an extension cable for the front slots, I exclude cabling as a problem. Then the BIOS settings came into my mind and they seem to have a small effect. Maybe some kernel professional can read something out of it.
Tested with these BIOS settings (used them for all tests above in this bug report): USB Legacy Mode: Auto USB 3.0 Legacy Mode: Enabled dmesg: [ 230.514236] xhci_hcd 0000:03:00.0: Timeout while waiting for a slot [ 280.683151] xhci_hcd 0000:03:00.0: Timeout while waiting for a slot [ 280.892975] usb 3-3: device not accepting address 2, error -62 [ 330.852059] xhci_hcd 0000:03:00.0: Timeout while waiting for a slot [ 330.852066] hub 3-0:1.0: couldn't allocate port 3 usb_device [ 380.987728] xhci_hcd 0000:03:00.0: Timeout while waiting for a slot [ 380.987736] hub 3-0:1.0: couldn't allocate port 1 usb_device [ 638.015783] xhci_hcd 0000:03:00.0: Timeout while waiting for a slot [ 638.015790] hub 3-0:1.0: couldn't allocate port 1 usb_device [ 730.086446] xhci_hcd 0000:03:00.0: Timeout while waiting for a slot [ 730.086453] hub 3-0:1.0: couldn't allocate port 4 usb_device ****** here I unplugged the hdd from USB3.0 port and plugged it into USB2.0 port ****** ****** the drive is mounted and works fine ****** [ 915.777382] usb 2-1.2: new high speed USB device using ehci_hcd and address 5 [ 916.003968] usbcore: registered new interface driver uas [ 916.010481] Initializing USB Mass Storage driver...
