Subject: Atombios Execution timeout

Hi Jerome,

On my laptop with a HD3650 GPU, during resume from RAM I get the 
below errors -

[   80.484213] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more 
than 1sec aborting
[   80.484218] [drm:atom_execute_table_locked] *ERROR* atombios stuck 
executing FA30 (len 493, WS 0, PS 4) @ 0xFA71
[   81.497547] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more 
than 1sec aborting
[   81.497552] [drm:atom_execute_table_locked] *ERROR* atombios stuck 
executing FA30 (len 493, WS 0, PS 4) @ 0xFA71
[   81.548053] PM: resume of devices complete after 2129.312 msecs
[   81.746649] PM: Finishing wakeup.
[   81.746651] Restarting tasks ... done.

Since this happens only during resume may be the current 1 second time is 
not sufficient for the resume case? I bumped it to 2 sec and it stopped 
complaining. 

May be we should increase the timeout for only the resume case?

Thanks,

Parag
