2.6.37-rc2-git7 regression: wine fails to start

[Jean Delvare]

Running 2.6.37-rc2-git7 on x86_64, wine fails to start. I get the
following error in the kernel logs:

radeon 0000:07:00.0: r600_cs_track_validate_cb offset[0] 0 2095360 4096 too big
radeon 0000:07:00.0: r600_packet3_check:1331 invalid cmd stream 484
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

Hardware is: 
07:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350]
07:00.1 Audio device: ATI Technologies Inc RV710/730

X.org version is 7.5.

With kernel 2.6.36, wine works just fine on the same system. Does it
ring a bell to anyone? Any clue how to investigate this bug? If not, I
can start a bisection.

I can also provide any additional data you need for investigation.
