After upgrading from X.org 7.2 to 7.3, my laptop's Radeon Mobility M10 shows garbled, fast changing patterns instead of the actual screen contents on the internal LCD. The laptop is a Dell Inspiron 8600C with a 15.4" 1920x100 LCD, running FreeBSD 6-STABLE. I have experimented both with driver version 6.7.192 included in X.org 7.3 and the driver from git HEAD. Both lead to corrupt display, while the driver from X.org 7.2 works fine. I have tracked this problem down to git commit 62f06d89da3f7160d5e4df8d7ce6fe1a94e9d07c. If I revert that commit, both the 7.3 driver and git HEAD produce correct output. Right now, I am running driver version 6.7.192 with that one commit reverted. Simply reverting a commit I know nothing about is not a solution, of course, but it seems to work around some bug introduced with that change.

I have just upgraded to 6.7.193 and the bug persists. Output is still a garbled semi-random pattern. Only fully backing out commit 62f06d89da3f7160d5e4df8d7ce6fe1a94e9d07c seems to work for me.

Please try ati git master or apply: 5e4d98470b6412a686883c554e7eb7badbe78c4d
I can confirm this is fixed in 6.7.195.
