Description Michael de Lang 2019-09-20 16:24:06 UTC

Using the soon-to-be linux 5.4.0-rc1 (574cc4539762561d96b456dbc0544d8898bd4c6e) with oibaf's ppa for DRI, I get the following messages in my kernel.log:

Music stops playing, desktop becomes completely unresponsive except for mouse. Mouse can be moved normally.

Hardware: Radeon RX 5700

See also https://bugs.freedesktop.org/show_bug.cgi?id=111481 were similar issues were reported.

For now, it seems that the only reliable workaround is to use the Mesa environment variable "AMD_DEBUG=nodma".

Much appreciated, will test that and if it seems to help, then this can be closed as duplicate.

Comment 3 Michael de Lang 2019-09-21 09:47:55 UTC

Confirmed workaround from #111481 to fix freezes.
