  • Radeon r300 3D broken in new mesa

    From Edward Robbins@21:1/5 to All on Tue Nov 22 02:00:01 2022
    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

    I reproduced this problem on my ibook G4 with radeon mobility 9550, and
    have filed a report here:

    Cheers,

    Worth noting: The eMac had problems with bad capacitors, which typically affects graphics before anything else (and hence this is my 4th machine!)
    The 1.42GHz model that I have does not appear to be affected, but as a precaution I wanted to rule it out so I booted mac OS X and ran quake 3
    arena for a few hours. I played a couple of games and then left it running overnight: It is buttery smooth in OS X and has rock solid stability, it's still running happily this morning. (Man, I forgot how good the colours are on CRTs... those blacks!)

    Later on I will try to see if I have similar issues on my radeon 9550
    based ibook, but would appreciate it if anyone can provide feedback about whether they have similar issues.

    Thanks,
    Ed

    machine!) The 1.42GHz model that I have does not appear to be affected, but as a precaution I wanted to rule it out so I booted mac OS X and ran quake 3 arena for a few hours. I played a couple of games and then left it running overnight: It is buttery

    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:<br><br>radeon 0000:00:10.0: GPU lockup (current fence id 0x0000000000001298 last fence id 0x000000000000129c on ring 0)<br>radeon: wait for empty RBBM fifo failed! Bad things might happen.<br>Failed to wait GUI idle while programming pipes.
    Bad things might happen.<br><br>(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:<br><br>xserver-xorg-video-radeon:1:19.1.0-2<br>firmware-amd-graphics:20200918-1<br>libdrm-radeon1:2.4.103-1<br>kernel: 5.5.0-1-powerpc<br>mesa: 20.0.2-1<br><br>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&#39;ve appended it to the bottom of this
    message).<br><br>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&#39;t a
    kernel bug - things are working with the latest kernel after downgrading mesa.<br><br>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 <a href="
