Public bug reported: Upstream stable release 4.4.34 introduced a regression that is already fixed in mainline but hasn't been applied to stable kernels yet (nor to Ubuntu kernels). Here's the thread where the bug was reported:
http://lkml.iu.edu/hypermail/linux/kernel/1611.2/04851.html Here's a partial transcript of the report: "This update broke PXE boot on our 4-way AMD boxes. The kernel panics in eth_type_trans(), presumably during kernel-level IP autoconfiguration, see [1]. Bisection points me at 5c67f947 (net: __skb_flow_dissect() must cap its return value). And indeed, reverting this commit fixes the problem for me." This issue is fixed with mainline commit: commit c9b8af1330198ae241cd545e1f040019010d44d9 Author: Eric Dumazet <[email protected]> Date: Tue Nov 22 11:17:30 2016 -0800 flow_dissect: call init_default_flow_dissectors() earlier ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Luis Henriques (henrix) Status: Triaged ** Affects: linux (Ubuntu Xenial) Importance: Undecided Assignee: Luis Henriques (henrix) Status: In Progress ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Xenial) Status: New => In Progress ** Changed in: linux (Ubuntu Xenial) Assignee: (unassigned) => Luis Henriques (henrix) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1645278 Title: Upstream stable 4.4.34 regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1645278/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
