[Dri-devel] BUG: DRI hangs on Radeon Mobility M6 LY

[Pawel S. <pawsa@TheoChem.kth.se>]

Hi,

I have a Radeon Mobility M6 LY (DIR disables TCL support for this 
card). When I try to resize a window containing a GL context, X server 
stops to respond to input events (keyboard and mouse). This may be 
related to resizing but also frequent update of the window. Following 
message is being logged:

[drm:radeon_lock_take] *ERROR* 4 holds heavyweight lock

This is 100% reproducible. Tested with snapshot 20020914 (i.e. today) 
but it happened earlier as well.

I can do some more tests if needed.

Pawel
