hello despite being extremely inexperienced with Linux i have used manjaro xfce for the past two years as my first operating system without issue across three computers; until the past 4 months with my primary desktop,
i have had horrible lockups at random in all applications in which mouse keyboard and power button and screen are all frozen, and if there is video or audio playing it will loop the last 2 seconds endlessly until i hit the reset button on my pc.
i also encounter boot issues, a grey screen with 3 dots willl appear and after a minute it will say
watchdog: BUG: soft lockup - CPU#11 stuck for 53s!
(with variation on the cpu# and the (x)s!)
which forces me to reset again, enter bios and boot from there. everything will work 2-8 hours until it freezes again, sometimes it will reboot first try other times it will fail to boot
i have read through this site for answers and i truly do not understand how to resolve this issue based upon other users input so far, i have tried updating everything and i still am experiencing the same issues. i did not update or changed bios or system settings in the first 6 months of flawless operation before the freezing began.
system info: kernal is 6.1.25-1 xfce AMD Ryzen 5 3600X 6-Core Processor PowerColor Red Devil AMD Radeon RX 6600 XT Corsair Vengeance LPX 32GB (2X16GB) DDR4 3200 ASRock X370 Killer SLI
i looked into Qjournalctl and identified the following errors but i do not know what they mean
kernel: Uhhuh. NMI received for unknown reason 21 on CPU 1.
kernel: Dazed and confused, but trying to continue
kernel: rcu: Possible timer handling issue on cpu=6 timer-softirq=4369

kernel: rcu: Unless rcu_preempt kthread gets sufficient CPU time, OOM is now expected behavior.

i apologize for my ignorance and hope someone can provide low skill instructions to fixing this issue
