avandeputte Posted March 17, 2022 Share Posted March 17, 2022 I've been experiencing occasional kernel panics. I haven't figured out a pattern / cause for them. I am not sure what logical next steps for troubleshooting. Hoping to get some insights from forum! FYI, I am on 6.10.0-rc3, but I had these with 6.9.x as well, I've never been able to capture the error before (took me a while to figure out the syslog to flash thing).
