Computer starts operating slow after crashing due to power outage. I need help debugging
Summary:
After an unscheduled restart my computer becomes an order of magnitude slower. If manually restarted afterwards, the computer reverts back to its expected performance.
Detailed description:
While the computer is running normally, this is the score it gets while running a standard geekbench score:
If the computer crashes, or loses power due to an electricity outage, and has to be booted normally back again it becomes super slow. If I run geeksbench again this happens: (an order of magnitude slower)
I have no ideia how to debug this problem. Can somebody suggest a plan of action to debug the situation?
Things I have tried:
- updating bios,
- switching processor
- trying a different graphics card
- using only on RAM stick
Specs:
- X399 GAMING PRO CARBON AC (MS-7B09)
- AMD Ryzen Threadripper 2970WX 24-Core Processor
- 32Gb Kingston DDR4 2400mhz (2x16Gb)
- NIVIDA 1080 gtx
EDIT:
Thanks to someone's answer I was able to extract logs regarding a good boot and a bad boot. Unfortunately I'm not able to find anything weird myself. Here they are:
Bad boot:
Good boot:
I removed timestamps to be able to compare them using: colordiff -y -W 256 broken.txt working.txt

Compare the startup logs of the two types of reboots. Use sudo journalctl --list-boots | tee boots.txt (very slow the first time you run it - journalctl has to index all the logs) to get the index number and sudo journalctl -b # will let you pick a boot from the list (# values are 0:current boot, -1:previous boot, -2:the one before that,...).
There will be a difference!
