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.
