           Summary: [radeon HD4250] Frequent lockups while screen locked
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: ydirson@altern.org


Created an attachment (id=36664)

Xorg log file, with nearly 30k lines of repeated messages stripped

Direct symptoms:
- display left unattended with xscreensaver in simple blank mode
- DPMS disabled (checked both with xset and xscreensaver-demo)
- when coming back to my keyboard the monitor does not get a video signal
- I can still login remotely through ssh and reboot the machine properly

Hardware is an Asus "M4A88TD-V EVO/USB3" motherboard, featuring radeon HD4250
(RS780).  OS is uptodate Debian/testing.

syslog contains lines like the following.  In this case, although I was not
here, it may be that someone tried to use the box.  In the 2 other occurences I
have traces for, it I may even have been myself, but I did not dig at that
time.

However, although the Xorg.0.log error lines are not timestamped, the file
timestamp itself matches the box' reboot.  Since there are ~15000 occurences of
the error, X may have been experiencing them since the error reported by the
drm module.  I can try to get more detailed facts next time (unless
unnecessary, just tell).

In older occurences (do not recall the precise set of events, although the
"wishing to unlock screen" event has always been the only way to see the
problem), the 3 error lines occur on a longer timespan, some in sync with the
clock (??):
