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- 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

Does any guy meet the same situation?
