Facing same issue on 6.6.10-76060610-generic on Pop!_OS 22.04 LTS using Dell Inspiron 15 7567.
Screen fails to recover after suspend/sleep giving this error, can't switch to ttys either, only solution is to force reboot, which is very annoying as I lose all my work from the session. I've seen several forums with this bug with open issue going back to several years but there seems to be no solution, is no one working on it ?... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-oem-5.14 in Ubuntu. https://bugs.launchpad.net/bugs/1973098 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.
