Public bug reported: Hi there, I've updated kernel on my Ubuntu 16.04 from 4.4.0-201-generic to 4.4.0.202-generic today and it broke my system. Basic commands, such as pidof, lsof, ps fax (ps -a works) hang indefinitely and not even root issued kill -KILL will terminate them. Only thing that helps is to kill the shell that started such commands.
I had to reboot back to 4.4.0-201, however during shutdown various stop jobs hanged as well and after more than 25 minutes I had to go for hard reboot. My current—NOT BROKEN—kernel has signature (cat /proc/version_signature): Ubuntu 4.4.0-201.233-generic 4.4.247 I am attaching the lspci-vnvn.log, also created with the non-broken kernel. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: xenial ** Attachment added: "lspci-vnvn.log created with the non-broken kernel" https://bugs.launchpad.net/bugs/1913853/+attachment/5458209/+files/lspci-vnvn.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913853 Title: Ubuntu 16.04 kernel 4.4.0-202 basic commands hanging To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1913853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
