I suspect the race condition may be in vss_on_msg() with the non-thread- safe variable vss_transaction.state.
And I guess the below patch may have fixed the issue (the patch hasn't be in the upstream yet): http://lkml.iu.edu/hypermail/linux/kernel/1510.3/04218.html I can only test the patch tomorrow. So it would be great if somebody can help to test the patch today, at your conveniement. Or, just wait my result. :-) -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
