Kernel-2.6.31.6-134 seems to have a bug on R600 DRM

[Liang Suilong]

After updating the package, compiz crashed and glxgears can not run.
However, KMS and plymouth can still run well.

Here is dmesg message that I grabbed:

[drm:r600_cs_packet_next_reloc_mm] *ERROR* No packet3 for relocation for
packet at 47.
[drm:r600_packet3_check] *ERROR* bad SET_CONTEXT_REG 0x28014
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

But I reboot with kernel-2.6.31.5-127. All the thing return to normal. My
desktop is running on Fedora 12 x86_64. My graphic card is HD3650.

ATi display drivers: xorg-x11-drv-ati-6.13.0-0.11.20091119git437113124.fc12
Kernel: 2.6.31.6-134.fc12.x86_64
Mesa: 7.6-0.15.fc12

Does any guy meet the same situation?
