Public bug reported: I installed ubuntu 20.04 in an Aopen DE6340 which contains an "AMD Ryzen Embedded V1807B with Radeon Vega Gfx" and the installation went correctly, but at the end at the moment of unplugging the iso and restarting the computer never restarts, appears periodically about hung task timeout and never restarts.
I tried in the installed system with Ubuntu 5.4.0-37.41-generic 5.4.41 and linux-image-5.4.0-28-generic and it's happening in both versions. With mainline kernel its working correctly until linux-image- unsigned-5.4.21-050421-generic_5.4.21-050421.202002191431_amd64.deb from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.21/, after 5.4.22 it's starting to happen the same. Maybe related: https://bugs.launchpad.net/ubuntu/+source/linux-meta- hwe/+bug/1880041 because there are a lot of coincidences, but the fix is released and continues happening. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883521 Title: Hang on shutdown/restart To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1883521/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
