Which version of FreeBSD, exactly?

freebsd-version -kru ; uname -aKU

pkg repos -el | sort -f

pkg repos -e | grep url

I'm not familiar with the meaning of T14, sorry.

Does the Wi-Fi hardware use iwlwifi(4)?

A kernel panic when waking from sleep might relate to the graphics driver.

Sorry I wasn't clearer before, the laptop is a Lenovo Thinkpad T14 gen3 with an Intel CPU. I poked around in logs a bit but I haven't found anything indicating an error yet.

EDIT: just started reading Ch. 10 on Kernel Debugging[1], will try some things and see if I can extract any useful information. The handbook is so great.

Thanks.

I have a vague sense that kernel panics with iwlwifi should have been resolved before 14.3-RELEASE. Bugzilla should be fairly close to definitive, expect info to be copious but well-organised.

Alder Lake-P GT2 [Iris Xe Graphics], it's harder to find information.

I spent around a year trying to pinpoint the cause(s) of apparently random failures with different (older) hardware. After switching to Kubuntu on the same hardware, I suspect that the issue with FreeBSD was ACPI-related.

If you have crash files from kernel panics: it should be possible to identify, but not necessarily solve, a problem.

They probably are telling you the model of laptop; ThinkPad T14
