[bisected] Radeon KMS bug(?) after Linux kernel 2.6.32 causes a crash of X server 1.8.0+ on termination

Nix nix at esperi.org.uk
Thu Apr 22 16:15:40 PDT 2010


[sorry for sending this to both the kernel and X lists, but after
bisection I still have no real idea where this bug might be. I'd open a
bugzilla ticket if I had any confidence that I'd open it in the right
place...]

On 21 Apr 2010, nix at esperi.org.uk uttered the following:

(The console is not merely unusable: the DVI signal turns off, and the
keyboard appears dead. The network is happy and I can shut down remotely,
but I can't do a chvt or start X again -- or rather I can try and nothing
visible happens.)

I've bisected the kernel half of this.

This is introduced by a commit predating 2.6.32's release but integrated
in the 2.6.33 merge window:

commit ed160143c6967e89aee05b0685e73c4103bb3e38
Author: Alex Deucher <alexdeucher at gmail.com>
Date:   Tue Dec 1 14:12:14 2009 -0500

    drm/radeon/kms: add tv standard property to tv connectors

    Lets user select tv-standard.  The property was there,
    just not hooked up.

    Signed-off-by: Alex Deucher <alexdeucher at gmail.com>
    Signed-off-by: Dave Airlie <airlied at redhat.com>

so I guess perhaps this is not a kernel bug, but merely a bug in the
TV_STD parts of xf86-video-ati --- but I didn't upgrade that, merely
recompiled it; xf86-video-ati master + xorg 1.7.5 + kernel 2.6.34-tip
works fine, as does xf86-video-ati master + xorg 1.8.0 + kernel 2.6.32.
It's only the combination xf86-video-ati master + xorg 1.8.0 + kernel
>2.6.32 that crashes on termination.

So maybe it *is* a kernel bug, or a latent bug in the driver causing
memory corruption inside the X server only when the kernel and X server
are new enough. (But this is starting to feel a bit unlikely to me.)


In a few days I'll bisect the X.org half of this, since 1.7.5 doesn't
crash on exit no matter which kernel I'm running. The last time I tried
to bisect the X server it was... painful. Let's see if it's any easier
nowadays...


My Xorg.log from 1.8.0 shows no sign of TV connectors, but the
dmesg log from 2.6.33 and later says I have them.
