Description Adam Williamson 2020-04-21 22:19:17 UTC
There's a known bug in kernel 5.6.5 which causes systems with AMD graphics adapters (not sure if it's really all amdgpu-supported adapters, or some subset) to hang on reboot. This bug was introduced in 5.6.5, so by pulling 5.6.5 into the F32 RCs to fix , we broke this. Some users reported running into this bug in the 5.6.5 update:

I'm filing this bug for consideration as an FE so we can pull 5.6.6 into the RC-1.5 compose instead and hopefully have both bugs fixed and no new ones introduced (crosses all available digits). We have a 5.6.6 build in Koji already.

Comment 4 Justin M. Forbes 2020-04-21 22:29:35 UTC
I would certainly consider this FE worthy, the kernel is built and submitted for testing, also as the rebase for F31, so it should get a decent amount of testing.

Comment 5 Adam Williamson 2020-04-21 22:29:44 UTC
That's +3 or +4 (if I count myself), setting accepted.

Comment 6 Adam Williamson 2020-04-21 22:30:24 UTC
Unfortunately we have to fire the RC like, right now, so we can't wait on testing first :/ we'll just build it and hope it's good! what could possibly go wrong (don't answer that)
