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.

  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.

    Yeah to your point earlier a graphics driver issue seems a likely suspect, still haven't found any evidence yet though. Will keep looking.
