Summary: regression in vt-switching between x servers with ums
radeon driver
QA Contact: [email protected]
Severity: normal
Classification: Unclassified
OS: FreeBSD
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: NEW
Version: 7.7 (2011)
Component: Driver/Radeon
Product: xorg
Software:
xorg-server-1.12.4
xf86-video-ati-6.14.6
One peculiarity of my setup is that I run two X servers. And the regression is
exactly about that.
Until a recent upgrade (from driver version 6.14.3) everything worked just
fine. But now if I do a direct VT-switch from one X-owned terminal to the
other, then I get a significant chance of my system hanging.
I see the following things when that happens.
In Xorg.log I sometimes get (repeated many times):
(EE) RADEON(0): Timeout trying to update memory controller settings !
(EE) RADEON(0): You will probably crash now ...
In system log I sometimes see (repeated many times):
info: [drm] wait idle failed status : 0xA0003030 0x00000003
Sometimes the system just resets without leaving any clues.
Here is another interesting point. If first I do a VT-switch to a non-graphic
(console) terminal and then to the other X terminal, then the problem never
happens.
Downgrading xf86-video-ati to 6.14.4 seems to fix the problem.
I haven't tried 6.14.5 yet.
I can do more bisecting / testing, but perhaps you would have some pointers on
things that I should try first.
