I regularly hit the below during resume from RAM - [ 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.
Bumping the 1sec timeout to 2sec cures it - does not seems to be impacting anything else.
