Random kernel panic? (related to wifi / networking?)

scippio · 2020-03-08 09:07:59

Hello, I have a problem with random kernel panic? (Caps lock started blinking) after some system upgrades (I don't know when exactly started this problem). Sometime system freeze after boot in seconds/minutes... for example 10 times in hour... sometime it's ok ok whole day. And I don't know how to get more informations I can't see any problems in logs. But it's maybe related with my network wifi/wpa_supplicant. Because I observe slowdown of my connection and some "mini-downtimes" to my wifi AP. Is possible get some kernel panic log or more informations somehow? thx.

UPDATE: It looks like the problem is only on my home wifi. At my office, everything works whole day. Is possible that kernel panic (I think it's kernel panic because caps lock blinking...) is related to my wifi/network connection? I tried downgrade wpa_supplicant but the system still freezing..

I: Kernel: Linux ghost 5.5.8-arch1-1 #1 SMP PREEMPT Fri, 06 Mar 2020 00:57:33 +0000 x86_64 GNU/Linux, wifi: iwlmvm, 02:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

I downgraded to kernel 5.4.x and everything looks fine now.

What is at the end of the journal for a boot that resulted in a kernel panic?

Relatively "nothing"... I can't see any Kernel Panic log... system just freeze and Caps lock blinking with power LED blinking.... After Kernel downgrade to 5.4.x all is stable now...

$ LANG=en journalctl -r
