Computer Randomly Freezes and Only Responds to Hard Reset [Solved]

ChrispyChris3 · 2024-04-28 21:19:28

I've been having this issue off and on for a while now and it's starting to really frustrate me. I'll be working along just fine and suddenly the computer completely freezes and nothing works at all no matter how long I wait. I have to press the hard reset button to reboot. I've checked for logs and the last journal but I'm not finding anything. At this point, I'm hoping someone can help me figure out what it is, or maybe give me some other ideas for things to check. I will say my hardware is old, about ten years, so maybe that's an issue, but I would hope I could see some sort of error somewhere if this is the case. I'll post the pastebin to the last log before this reboot. I don't see anything explaining the problem, but maybe I'm not sure what I'm looking for. If you need any other info, I'd be more than happy to provide anything you need.

journalctl -b -1
hwinfo --short

Try avoiding pressing the power button to hopefully be able to flush more of the journal to disk, by enabling SysRq and rebooting with the REISUB sequence, leaving a few secs between each key press: https://wiki.archlinux.org/title/Keyboa … el_(SysRq)

Wow, thanks for this information. I've never even heard of this or come across it in all of my Googling. I have one more quick question as I just dealt with another freeze tonight when I got home and I did a hard reset sadly, but going forward I want to accumulate as much information as possible. I am going to issue this command in my terminal so it's active just for one session anyways to start (I'll think about making it permanent later):

sysctl kernel.sysrq=1

. Do you recommend a reboot immediately if I freeze, or should I try a SIGTERM, flush data to disk, or another of the commands? I've tested and I can access the commands on my computer, so I'm just curious what might help you guys if I need to post back with more info after a freeze.

Thanks for your help!

nb. that

sysctl kernel.sysrq=1

isn't persisntent and will not survive any reboot (ie. don't forget about it if you perform a regular reboot)

When the system freezes, do the entire REISUB mnemonic - particularly the "S" is really important.

Cool, I went through the entire REISUB process after a system freeze yesterday. I'll post a link to the last journalctl boot entry. If there is more information that would help, please let me know and I'll pull those logs as well. I see some out of memory stuff, so I'm beginning to wonder if that is the issue. Thanks for your help!

journalctl pastebin

Thanks a bunch, I appreciate you confirming and helping, it means a lot. I'll work to be better at using less tabs haha. Have a great day!
