Public bug reported: I do not know how to reopen this bug https://bugs.launchpad.net/ubuntu/+source/libatasmart/+bug/445852 so I decided to create new bug.
After recent update of Kubuntu 14.10 (beta), and following reboot, I got these messages in dmesg [ 1.534737] ata14.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 [ 1.534758] ata14.00: irq_stat 0x40000001 [ 1.534771] scsi 13:0:0:0: CDB: [ 1.534772] Inquiry: 12 01 00 00 ff 00 [ 1.534776] ata14.00: cmd a0/01:00:00:00:01/00:00:00:00:00/a0 tag 3 dma 16640 in res 00/00:00:00:00:00/00:00:00:00:00/00 Emask 0x3 (HSM violation) [ 1.534816] ata14: hard resetting link Full dmesg: http://paste.ubuntu.com/8434914/ ** Affects: libatasmart (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1374595 Title: Emask 0x3 (HSM violation) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libatasmart/+bug/1374595/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
