LL5.2 slowing down, erratic behavior and freezes both in booting and performance

[litecub]

Hi,

I am a LL newbie, so maybe I am doing something wrong. Any help would be appreciated.

I have Linux Lite 5.2, multiboot, on my notebook (for specifications please see the end of my post). I am using LL since a few weeks along with Ubuntu 18.04, Debian 10 and 11 and Windows 10. Bootup speed and performance were ok first, but lately booting takes ages, shows a lot of "FAILED" lines until it reaches login; and after that the system freezes occasionally unexpectedly, sometimes so stubborn that <Ctrl>+<Alt>+<F2> has no effect at all and only a hard switch off is a rescue. Generally, the performance during normal use is slower. The other multiboot distros seem to be unaffected (only Win10 has been always slow, anyway).

What could be the reason and could that be amended, please?

Thanks, litecub

P.S. I detected the "FAILED" lines after changing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="" in /etc/default/grub.

P.P.S. Neither the Preview button nor "shift+alt+p" to preview have any effect on my forum thread

Here are only the "failed" lines from dmesg. If anybody here could help, I have more in store.
