--- Comment #29 from AmarildoJr amarildosjr@riseup.net --- I just tested the oldest firmware available in the Arch Linux Archive, namely linux-firmware 20130725-1, and the crashes don't happen. This is with current Arch, not a single package is old and all packages are up-to-date according to the repos.
I'm hitting 10 to 30 FPS in-game, but at least the crashes don't happen which IMO is a very good sign of where the problem might be.
I'll report the firmware problem to AMD.
In the mean time, does anyone know how I can try running the firmware from Catalyst?
@Marek, where is the best place to report this?
