linux_kernel_3.14-rc2_dmesg

I have a laptop with Radeon HD6520G GPU. 

I am running Arch Linux 64 bit with Linux 3.14-rc2 kernel and Mesa 10.0.3

During shutdown, suspend and resume, GPU hangs and I get error messages in the
kernel that state:

[drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting
[drm:atom_execute_table_locked] *ERROR* atombios stuck executing D05E (len 62,
WS 0, PS 0) @ 0xD07A

Earlier, shutdown would work fine, and laptop would also suspend quickly. 

However now I find that suspend and shutdown take a long time and I see the
above error messages.
