fglrx hangs on shutdown

Hi all,

I am having an issue with computer hanging on shutdown right after "removing addresses" for net.eth0. If I wait for like 3 minutes (long time to wait!), shutdown continues, and after booting up again I see in /var/log/messages a long output of issue with fglrx, something about ASCI hang. The whole thing is below:

It appeared after some recent updates. Does anybody else has this problem? And despite fglrx is an ati binary blob that nobody wants to work with, is there any way to work this issue around?

Just in case, my emerge --info:

Usually the best chances for a quick fix is trying an older/newer kernel or newer drivers.

Khumarahn · Post by **Khumarahn** » Tue May 24, 2011 2:50 am

Thanks for advice, I tried newer version of ati-drivers already, but didn't try other kernel or older drivers.

BTW, I forgot to mention that my computer has 2 video cards, it actually works as multiseat.

Another thing to try is turning off graphical framebuffer for the console if you have it on. There's been a history of problems in combination with X drivers.

@BradN,

your advice to try other kernel versions helped. In combination of newer kernel-2.6.28-gentoo-r5 and newer ati-drivers-11.5, system doesn't hang on shutdown anymore

This is strange however that part of issue remained - right before power goes off, it says something like "cannot remount / readonly because we are using it". I can tell that this is related because if I, say, remove one of video cards, it never appears. Thus, something must be wrong, even though it doesn't bother me that much now that it doesn't make me wait a lot.

Khumarahn · Post by **Khumarahn** » Wed May 25, 2011 5:47 am

forgot to add - I didn't use framebuffer at all

BradN · Post by **BradN** » Wed May 25, 2011 5:28 pm

Strange, the unable to remount / read-only normally only happens when you've done unusual mounting procedures (and the system can't figure out the right order of unmounting things) but most likely a program is hung up in a kernel call and unable to fully exit (holding some read/write files open).

It'd be interesting to see a ps -Af output at that point in the shutdown sequence (maybe you could add it to the init script along with a long enough sleep command to read the output).

Just an idea anyway because the system keeping / mounted read/write during shutdown often leads to lots of extra disk checking at boot up (maybe depending on filesystem)

/usr/bin/Xorg :0 -nolisten tcp -layout seat1 -sharevts -novtswitch -isolateDevice PCI:5:0:0 -auth /var/gdm/:0.Xauth -nolisten tcp vt7

Sure enough, X hasn't fully exited. At least that's narrowed down to the source of that behavior (although it could be in combination with video related kernel drivers or other things)

Yes... Is there anything I can try to narrow it further?

BradN · Post by **BradN** » Wed May 25, 2011 11:57 pm

Honestly, I wouldn't know where to start to tackle that in a proper debugging method (I suspect it would require lots of knowledge of how X.org interfaces with video drivers, and maybe how fglrx interfaces with the linux kernel).

Best thing to do is look for / file a bug report and keep trying new software versions (drivers, kernel, X.org) until someone fixes it.

That ASIC hang message could have something to do with things, basically saying the video card stopped processing requests and probably some reset had to be performed or drop down to less acceleration features. It's not unlikely that the ATI driver doesn't handle these cases well, and that could be what's hanging up (some kind of call into kernel mode that's waiting for the device, but never returns).

BradN, do you know where would be best to submit bug report on this?

Overall, thank you much for your help.

BradN · Post by **BradN** » Fri May 27, 2011 4:49 pm

I would try looking on bugs.gentoo.org first to see if there are any hangs at shutdown or hanging X processes reported like that, and report a bug there if you can't find one.
