Title:
[i915] Intermittent freezing and LSPCON init failed kernel messages
Status in linux package in Ubuntu:
Confirmed
Status in linux-signed-oem-5.14 package in Ubuntu:
Confirmed
Bug description:
Hardware: Lenovo ThinkPad model 20ST0055AU
Boot messages show:
[ 6.397804] [drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon
[ 6.397901] [drm] Initialized i915 1.6.0 20201103 for 0000:00:02.0 on
minor 0
During normal operation there will intermittently be a freeze for a
second or two and then more of these messages display in the kernel
logs:
[ 505.487006] [drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon
[ 505.487072] [drm:lspcon_resume [i915]] *ERROR* LSPCON init failed on port D
[ 506.747930] [drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon
[ 506.748018] [drm:lspcon_resume [i915]] *ERROR* LSPCON init failed on port D
The system will then become operational again.
The system is still usable, but it is annoying.
I've switched onto this OEM kernel from the generic kernel (5.13), as
I had other problems with 5.13 regarding external displays not coming
back after idle timeouts.
