Bug 12294

Created attachment 11439 [details]
X.org log (the switches from and to the vt has been emphasized)

Can you try again with ati git master?

I compile (almost) daily the git master since the randr-1.2 branch was merged into it, and the problem is still there :( when X.org starts, the system is not able anymore to switch to "text" mode.

Any change with current ati git?

Sorry, I forgot to "ping" this bug.

The issue is still there (Xorg 7.4 from debian experimental packages, radeon driver from today's git).

The messages written in Xorg.0.log during vt switch are slightly different from the ones I reported:

Changing to VT:

(II) AIGLX: Suspending AIGLX clients for VT switch

Is this still an issue with kms or newer versions of the driver?

> Is this still an issue with kms or newer versions of the driver?

Yes, it is (sorry for my lack of updates), but with KMS is different. I'm currently using Debian Squeeze:
xserver-xorg-video-radeon 1:6.13.1-2
xserver-xorg              1:7.5+7
xserver-xorg-core         2:1.7.7-8
libdrm2                   2.4.21-1~squeeze3
linux-image-2.6.32-5-686  2.6.32-26 (it contains drm from 2.6.34)

When KMS is turned on (default behaviour), the flickering stars when (I think) the kernel module is loaded (I don't know if radeon or drm) and when Xorg starts, the flickering is fixed (just like Xorg change some values) and virtual consoles work again.
How can I help to debug this issue?

from .33 (plus various fixes) actually.
