Summary: [r600] radeondrmfb rendering is broken and running X
makes GPU lock-up on RV770 CE (Radeon HD 4730)
Product: Drivers
Version: 2.5
Kernel Version: 2.6.38
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
AssignedTo: drivers_video-dri at kernel-bugs.osdl.org
ReportedBy: virtuousfox at gmail.com
Regression: Yes
with 2.6.37 it's all OK but since 2.6.38 from very framebuffer initialization
screen is filled with dense grey lines looking like ugly grid. also per every
3cm on my 1920x1080/23' screen there is a distinctive whitish vertical line.
when X try to startup i can see cursor and can move it around for a while (that
grey grid is there too) but kdm does not starting up and GPU locks up.
it is the same with 2.6.39. here is `dmesg|grep drm` for 2.6.39:
