Hi, I have a 2TB Seagate Backup drive that works fine when used in my laptop's USB 2.0 port yet when plugged into the USB 3.0 port my system hangs with a Kernel Panic/GPF and needs a hard reset. I'm running Fedora 20 on an ASUS UX31E laptop. I've just upgraded from the base release kernel 3.11.10-301.fc20 straight to 3.16.2-201.fc20 and the problem appeared. (new laptop install hence the large jump). Rolling back to the 3.11.x kernel lets the drive work again. I tried a few newer 3.16.x kernels (and some slightly older ones 3.15.x) but the problem still exists. I've since been able to work around the problem by blacklisting the UAS driver, which lets me plug in the device without a fault, but doesn't recognise the drive for use. I've now settled on using an Option rule in modprobe.d directory to force the device down to the usb_storage driver instead of UAS. This now works fine with no problems on 3.16.2-201 kernel however, it is not the newer driver. I'm fairly sure this is coming from the UAS driver, although we can never be certain... I also noticed that there have been a few of these issues before (http://www.spinics.net/lists/linux-usb/msg109480.html) so whilst i've been able to work around it, i'm still keen to stick around and help you guys out and fix the problem - where i can. I appreciate your work and please let me know if there is anything I can do to help. (I've pasted relevant logs below) Alan Barker. ------------ [Kernel messages] Sep 25 22:10:51 holon2.local kernel: usb 3-1: new SuperSpeed USB device number 6 using xhci_hcd Sep 25 22:10:51 holon2.local kernel: usb 3-1: New USB device found, idVendor=0bc2, idProduct=ab20 Sep 25 22:10:51 holon2.local kernel: usb 3-1: New USB device strings: Mfr=2, Product=3, SerialNumber=1 Sep 25 22:10:51 holon2.local kernel: usb 3-1: Product: Backup+ SL Sep 25 22:10:51 holon2.local kernel: usb 3-1: Manufacturer: Seagate Sep 25 22:10:51 holon2.local kernel: usb 3-1: SerialNumber: NA75VFTG Sep 25 22:10:51 holon2.local kernel: scsi10 : uas Sep 25 22:10:51 holon2.local kernel: scsi 10:0:0:0: Direct-Access Seagate Backup+ SL A905 PQ: 0 ANSI: 6 Sep 25 22:10:51 holon2.local kernel: sd 10:0:0:0: Attached scsi generic sg1 type 0 Sep 25 22:10:51 holon2.local kernel: sd 10:0:0:0: [sdb] Spinning up disk...
