I re-read comment #21, and you 'Saw none' of the errors with 4.0, which means this bug might be fixed there. It might be better of to perform a 'Reverse' bisect to identify the commit that fixes this bug and requested it in the prior stable kernels.
Can you test the following kernels and report back? We are looking for the last kernel version that has the bug and the first that does not: v4.0-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-rc1-vivid/ v4.0-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-rc2-vivid/ v4.0-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-rc3-vivid/ ** Tags added: performing-bisect -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1371233 Title: USB 3.0 connection is unreliable + xHCI xhci_drop_endpoint called with disabled ep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1371233/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
