...this time with the 6.14.0-27-generic kernel. Running X11 on a system that is dual-bootable to both Kubuntu and Win11. (I rarely run Win11.) I was viewing the SanDisk and Yahoo Mail websites using Chromium in incognito mode (because I hate leaving cookie crumbs for others to follow). NetworkManager started acting up, consuming 100% of a single CPU, during which time the NetworkManager icon on my taskbar went orange-red. (I run both LAN and WiFi on this desktop.) The ifconfig command hung. I performed "top" to see NetworkManager at 100% and to obtain the NetworkManager PID. I then attempted to kill NetworkManager using "sudo kill <NetworkManager PID>, but the "sudo" command hung. (All "sudo" commands hung during this time which is likely not a clue but only a symptom.) However...and this is the only time I've _really_ needed to do this...I previously set a password for root and I was able to become root via "su". As root, I then killed the NetworkManager PID. All was allegedly back to normal. I then performed "shutdown -r", but found that processes associated with fwupd-refresh.service, postfix@.service and cups-browsed.service refused to die until MUCH later when the operating system finally sent SIGKILL. And just as before, while the system did shutdown, it did not power off the hardware, leaving up a display stating that /dev/sda needed to perform some cache saving or something similar...and /dev/sda was NOT mounted and is essentially NEVER used, since I run a SSD. As such, the reboot required by "shutdown -r" did not occur.
Also, my Plasma display sometimes crashes but recovers. Yes, it is annoying.
1. Let me know if I need to post this elsewhere in kubuntu forums.
2. Could this nonsense be caused by UEFI/BIOS settings?
3. Tell me exactly what information you need from me. Here is what is returned by "inxi -xxz -F":
Thank you very much in advance!
