Thomas Debesse (illwieckz) wrote (last edit ): Re: Linux 5.19 amdgpu: NULL pointer on GCN1 and invalid load on GCN2

So to summarize:

with Linux 5.19.0-42-generic amdgpu on GCN2: kernel NULL pointer dereference

- no display
- stuck boot requiring SysRq+K to continue
- errors in dmesg
- reboot requiring SysRq+B to continue

with Linux 5.19.0-42-generic amdgpu on CGN1: kernel UBSAN invalid load, load of value 8 is not a valid value for type '_Bool'

- no display
- errors in dmesg

Both GCN1 and GCN2 devices work with older revisions of the 5.19.0 kernel

I haven't reproduce the btrfs issue with Linux 5.19.0-42-generic so I'll ignore that issue and consider it fixed.

The amdgpu regression is still there and strongly breaking the usability of Ubuntu.
