52f518a3a7c2f80551a38d38be28bc9f335e713c is the first bad commit Full bisect log attached.
A couple of notes: 1. Often the bug is not reproduced the first time the system is booted with a given kernel version. Subsequent boots reproduce the bug. 2. In order to get bootable kernels from commit 9dda1658a9bd450d65da5153a2427955785d17c2 and onwards during bisecting I had to manually apply commit 425be5679fd292a3c36cb1fe423086708a99f11a. Otherwise the system gets stuck on "Loading initial ramdisk". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581777 Title: igb transmit queue times out To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1581777/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
