Description: Ever since kernel 5.5.2 was released, some strange problem with booting up and sleeping appeared. With booting, after listing all of the processes started the white underline cursor remains on a black screen for too long. Sometimes it stays there for 20-30 seconds and then the system starts up and sometimes it doesn't start up at all and I have to reboot the computer until it does. With sleeping the problem is this: I've set a key on the keyboard to sleep (suspend to ram) the system and pressing the key most of the time does nothing. When it does, it needs at least 10 seconds before the system gets suspended to ram. I had to switch to Arch LTS in order to get rid of these problems.
None of these things were happening in kernel 5.5.1 (in 5.5.1 or earlier versions I rarely saw the underline cursor and sleeping used to happen instantly) but unfortunately IDK enough to downgrade all the necessary packages and get 5.5.1 back (downgrading just "linux" and "linux-headers" doesn't do the trick).
At first I thought it was a systemd issue since Arch wiki suggested so, but systemd guys said this was a kernel issue, so I'm posting it here.


Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:
With the latest kernel simply reboot the system several times and the boot problem is bound to happen.
For the sleep problem: either use the menu function or use a hotkey to suspend the system to ram (not hybrid sleep or hibernate).
