    Exclamation Since 19.04 Upgrade System Locks Up Daily and Restart Hangs

    I upgraded to 19.04 a couple of weeks ago from 18.04 (via 18.10) and have been experiencing system lockups where everything freezes and I have to restart system. When I restart it hangs while starting all the services (Usually Gnome Desktop Manager...but not always). I have to literally power the whole thing down and start back up to get it to boot. I have been looking at the log files and see this error

    sender : lircd
    Error: No /sys/class/rc/ devices found

    It repeats hundreds of times even while the system is up. I could find almost nothing about it online
    (in the 20 mins since I posted this it now appears 2250 times)
    My system is as follows
    AMD Ryzen 7 1700x eight core
    Nvidia GeForce GTX 1050 Ti/PCIe/SSE2
    Driver 418.56
    32 Gigs Memory

    It happens when I am working on the system and sometimes when its idle. I dont know where to look so if there is more information I can provide let me know and I will do so
    I'm considering a clean install and just reinstalling what I need but would rather avoid that if possible

    From the rescue grub mode, use the command line to clean the system first (clean/autoclean/autoremove) if you have not already done it.

    I had tried that. Going to do a clean install today and see if that fixes it. I usually always do a clean install...why I didnt this time, I dont know. Guess you have to re-learn these lessons from time to time. I've never had success with upgrades. I'll post later if this solves my problem

    Finished clean install and reinstalled any apps I needed, and 2 restarts since no hangs...so here is hoping I'm good at this point

    I ran boot-repair to get system summery if that helps

    It just happened again but I was able to get the last 2 log entries

    systemd-udevd.service: Killing process 477 (systemd-udevd) with signal SIGABRT.
    systemd-udevd.service: Watchdog timeout (limit 3min)!

    This is happening on a daily basis...sometimes multiple times

    I finally fixed this myself by looking around elsewhere. Seems you have to disable Wayland in

    sudo gedit /etc/gdm3/custom.conf

    and remove the # in front of
    #Wayland = false
    to
    Wayland = false

    I've had 3 successful boots so I'm guessing that solved it
