https://bugzilla.kernel.org/show_bug.cgi?id=206235 --- Comment #1 from Steffen Nurpmeso (steffen@xxxxxxxxxx) --- Hello. I am now on 4.19.107 and "it happened again". Semantic was slightly different, i realized the notebook is not going to sleep, and found un-KILLable bluetoothd and rfkill instances, i even had to shutdown the computer hard. The following listing can be better understood with a snippet from my /root/zzz.sh that is invoked if acpid emits LID (close) events: while :; do down_off lid_exists || break sleep 1 lid_is_open && break done Here is the /var/log/kernel snippet: Mar 7 02:14:37 kent kernel: ------------[ cut here ]------------ Mar 7 02:14:37 kent kernel: kernel BUG at mm/slub.c:294!
