I should have added that this bug also causes the system to overheat badly even in sleep mode. It seems it causes the system to wake up. I got in the habit of powering it off when traveling because I found it almost too hot to touch a couple of times when I took it out of my backpack. -- You rece

This issue is only present for me when a micro-SD card is plugged in, whether it is mounted or not. System is LG-Gram, running fully up to date 22.04.3, running 5.15.0-83-generic kernel as of today. Completely reproducible. -- You received this bug notification because you are a member of Kernel
