Public bug reported: Coming from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1276705 .
Commit 786235ee in the upstream kernel made kthread_create() return immediately upon SIGKILL. On several machines, device initialization phase takes more than 30 seconds before kthread_create() is called. Since systemd-udevd unconditionally sends SIGKILL upon hardcoded 30 seconds timeout, boot is failing upon such machines. The conclusion of LKML discussion seems that we should fix systemd-udevd side rather than fixing kthread_create() side because hardcoded 30 seconds timeout is considered as a bug of systemd. Therefore, please consider allowing configurable (or at least much longer) timeout for systemd-udevd worker process. ** Affects: systemd (Ubuntu) Importance: Undecided Status: New ** Tags: trusty -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1297248 Title: Wait timeout for systemd-udevd worker process is too short To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1297248/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
