Here's a thread where people are seeing similar hangs on similar hardware under Linux:
https://bugs.freedesktop.org/show_bug.cgi?id=108900 "VERIFIED WONTFIX" because the kernel driver is probably closer to the issue, not Mesa here's another: https://bugzilla.kernel.org/show_bug.cgi?id=201957 The "fix" in the second one seems to be downgrading to an earlier firmware. Perhaps you can try to do that, the older radeondrm firmwares should be available from http://firmware.openbsd.org/firmware/6.8/radeondrm-firmware-20181218.tgz You can just unpack various versions and place the appropriate files under /etc/firmware for quick testing... I have no idea if the 20181218 is the right version to test, it may not be. It's just the first earlier version available on firmware.openbsd.org. You may need to grab a different version from a Linux repository.
