Hi everyone!
I just updated my eMac 1.42GHz with radeon 9600 for the first time in... perhaps a couple of years. Funnily enough just before I updated I was trying to get openarena to run, and found that it crashes my machine after the main menu appears or just before, with some errors:
radeon 0000:00:10.0: GPU lockup (current fence id 0x0000000000001298 last fence id 0x000000000000129c on ring 0)
radeon: wait for empty RBBM fifo failed! Bad things might happen.
Failed to wait GUI idle while programming pipes. Bad things might happen.
(gathered from a tail on /var/log/messages just before the crash), closely followed by a blank screen and dead ssh, requiring a reboot. However kodi ran fine and glxgears showed 800-900 fps so 3D was mostly working. I have some version numbers for where I was previously:
xserver-xorg-video-radeon:1:19.1.0-2
firmware-amd-graphics:20200918-1
libdrm-radeon1:2.4.103-1
kernel: 5.5.0-1-powerpc
mesa: 20.0.2-1
After updating I am on kernel 6.0.0-4-powerpc and mesa 22.2.4-1 and although X runs, attempting to do anything with 3D results in the screen flashing on and off, and X goes dead. However ssh stays alive and I can see some repeating output in dmesg (I've appended it to the bottom of this message).
I tried booting up with my old kernel, and everything is still broken. Downgrading mesa and libdrm does get everything working again (as well as it did previously anyway - openarena still causes a total system crash). This isn't a kernel bug - things are working with the latest kernel after downgrading mesa.
Has anyone else experienced this/know of a relevant bug report/workaround/mailing list chat? A quick search has only shown up some pretty stale bug reports on
freedesktop.org.
Thanks,
Ed
