I can see a possible issue with that commit. For an invalid sense value, sense_deferred with remain 0. and thus trigger the special logic.
>From the rest of the code sense_deferred seem to only be valid in the case when sense_valid, but that is not checked. Given the large amount of invalid sense output from hyper-v virtual machines, they would be very likely to trigger that exact code path. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1470250 Title: [Hyper-V] Ubuntu 14.04.2 LTS Generation 2 SCSI Errors on VSS Based Backups To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1470250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
