I have a Ryzen 7 4700U (laptop class) mini PC running 20.10 impish (with ubuntu studio sources and packages added). With the 5.13.0-23 kernel (I use the lowlatency kernel) update I started seeing an (approximately) 2 minute hang during boot if I hit F12 all I see is: '/dev/nvem0n1p2: clean...' during the hang after which it seems to proceed as normal. Once booted, everything seems to work fine. Additionally when I shutdown the system hangs (pressing F12 has no effect and the splash screen freezes: I have to power the computer down manually.
I installed the 5.13.0-25 kernel (again, low latency) update but the problem remains unchanged: same long hang on boot, same indefinite hang on shutdown. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1956401 Title: amdgpu hangs for 90 seconds at a time in 5.13.0-23, but 5.13.0-22 works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1956401/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
