Since updates Saturday night I have been having hard lock ups. It looks like Firefox is the trigger.
Lenovo X140e notebook
F35 current with all updates as of Saturday night.
Xfce desktop
It was really bad at first. I finally managed to kill Firefox auto load pages by in a non-graphics session, watching what top was reporting going on in the graphics session and killing Firefox.
Then starting Firefox and closing all my windows as they open. Finally got it to start up with nothing to open. That was this morning. Things seemed to be working OK until now when I got to my Hilton hotel for the night and going through their miserable portal that FIrefox would not accept their cert, and then it locked again.
Just booted. Updated again and only got added:
Upgraded: alsa-sof-firmware-2.1.1-1.fc35.noarch mariadb-connector-c-3.2.7-1.fc35.x86_64 mariadb-connector-c-config-3.2.7-1.fc35.noarch pipewire-0.3.52-4.fc35.x86_64 pipewire-alsa-0.3.52-4.fc35.x86_64 pipewire-gstreamer-0.3.52-4.fc35.x86_64 pipewire-jack-audio-connection-kit-0.3.52-4.fc35.x86_64 pipewire-libs-0.3.52-4.fc35.x86_64 pipewire-pulseaudio-0.3.52-4.fc35.x86_64 pipewire-utils-0.3.52-4.fc35.x86_64 Skipped: python3-reportlab-3.6.10-1.fc35.x86_64
I can't tell where, in /var/log/messages the system locked and then I rebooted. I did not note the times closely.
Anyone hear anything like this? So far can't find anything in bugs.
