System freeze when power cable unplugged Status in linux package in Ubuntu: New Bug description: I'm using KDE Plasma on Ubuntu 21.10 with kernel 5.13.0-19. Recently, my laptop has been freezing upon unplugging the power cord. The sysrq keys do not work when this occurs. When I switch kernels, the problem does not occur. The following kernels do not freeze when I unplug the power cable. * kernel 5.14.12 from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14.12/ * kernel 5.13.19 from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.13.19/ When I boot back into the 5.13.0-19 kernel, the problem recurs. I had also tried changing various system settings, bios settings, and packages, none of which made any difference, aside from switching kernels.
