Description:
After upgrading kernel from 4.8.13 to 4.9, my laptop randomly gets frozen. The time is about 1~2 minutes after boot completed. Downgrading to 4.8.13 and everything is fine. Unlike `dmesg` output is attached. Approaches tried: 1. In dmesg log, [ 245.404952] INFO: task systemd-hostnam:405 blocked for more than 120 seconds. [ 245.405014] Not tainted 4.9.0-1-ARCH #1 [ 245.405044] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. So I `sudo mv /usr/lib/systemd/systemd-hostnamed{,.backup}`. After reboot system freezing is still. I guess systemd-hostnamed is also a victim rather than the cause 2. According to https://bbs.archlinux.org/viewtopic.php?id=134249, tried to disable IPv6. Still freezing Additional info: Software: testing/linux 4.9-1 core/systemd 232-6 testing/linux-firmware 20161222.4b9559f-2 extra/zsh 5.3.1-1 Hardware Laptop: Acer Aspire E1-571G CPU: Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz Steps to reproduce: 1.

I've using 4.9.1 for several days and apparently the kernel bug
has already been fixed. This issue may be closed.
