Title:
Frequent hangs / lockups with "[drm:intel_pipe_update_end [i915]]
*ERROR* Atomic update failure on pipe A"
Status in linux package in Ubuntu:
Expired
Bug description:
Fairly recently I got an old HP Pavillion 14 laptop and installed
Kubuntu 17.10 on it. As far as I recall it ran fine, however, not long
after I upgraded to 18.04 and noticed frequent freezing (approx every
few hours). When this happens, all of a sudden, the screen just stays
with it's image immobile and unchanging. There is no visual corruption
onscreen and even the cursor does not move. Ctrl+alt+F[1-9] and
alt+ctrl+sysrq+RSEINUB do nothing.
Often when I look at the logs, at the end of kern.log.1 I see:
[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on
pipe A (start=96545 end=96546) time 394 us, min 763, max 767, scanline
start 760, end 778
Sometimes, earlier on, there is also:
Could not find key with description: [d4628bf1c812c861]
process_request_key_err: No key
Could not find valid key in user session keyring for sig specified in mount
option: [d4628bf1c812c861]
One or more global auth toks could not properly register; rc = [-2]
Error parsing options; rc = [-2]
I tested, and this also occurs in a brand new live usb of 18.04, and
noticed that it still happens there, even before any upgrades or
installation of packages (such as the wireless driver).
Other than the wireless driver, there are no proprietary drivers
installed (eg Nvidia, FGLRX etc).
Is there any more info I can provide to help troubleshoot this?
