I think Trixie is stable now but it is still doing about once a week that thing where if I close the laptop and later open it back up again the kernel will be panicked. I am still not sure how to go about filing this. I talked to the IRC channel and their most useful feedback was "connect a serial cable to get panic information that doesn't make it into the logs" which would be very useful if (1) the panic event can be triggered to happen on demand (2) my computer had a serial port

Apparently there are serial headers on my motherboard. … somewhere. I'm not sure if you can use them without soldering

@mcc ubuntu has linux-crashdump. I found these instructions for Debian 12 https://www.cyberciti.biz/faq/how-to-on-enable-kernel-crash-dump-on-debian-linux/It may be possible to USB but I haven’t found how recently. I think it’s changing the console on the boot line, but that doesn’t sound right to me.On IRC I usually answer several questions and am left with no answer to my question. I’ve given up there.

@drewdaniels I thiiiiink I did this and it didn't help because the hard drive is not available at panic time. I will review this post when I'm back on my laptop tho

@mcc @drewdaniels sometimes just ssh into the machine and have it run dmesg -w would do.

@mcc “reportbug” will likely help you on reporting the kernel bug. https://wiki.debian.org/DebianKernelReportingBugs is a starting point on getting details, but I think you’ve done most of what you can from those (might be worth a double check).

@shironeko @drewdaniels will that work while the machine is asleep?i can believe ethernet might come up before the hard drive but that doesn't mean the sshd process will come up early enough to send the packets

@mcc @drewdaniels might be worth a try if the issue can be reproduced by just going to sleep and waking up right away.
