Created attachment 255963 [details] Log files from /var/crash and lspci I had two similar kernel panics in 4 days. It's apparently caused by or triggered by the processing of incoming UDP packets. The source(?) port appears to have been 43780 in both cases. Looking through the backtrace, I cannot easily explain this. # uname -a FreeBSD thinkpad-x270 14.2-RELEASE FreeBSD 14.2-RELEASE releng/14.2-n269506-c8918d6c7412 GENERIC amd64 This bug never ever happened on 14.1, pointing to a regression. I attached `lspci -vvxxx` as well. The network driver is em(4). Next, I will try intel-em-kmod. Since I219-LM is not a particularly rare adapter, I assume this might affect many people. I have the vmcore files as well, but they are large (around 2GB), so I will upload them somewhere only on request.
It cannot have anything to do with the ethernet driver, since I wasn't connected via ethernet, but via wifi (if_iwm), which is also apparent from the backtrace. So it might have something to do with this driver. I doubt so however since it did not change between 14.1 and 14.2.
Hi! Can you please share the core file in a private email to me? You may use my PGP key to encrypt your mail: https://docs.freebsd.org/en/articles/pgpkeys/#_gleb_smirnoff_glebiusfreebsd_org
(In reply to Gleb Smirnoff from comment #2) I am a bit afraid, that these dumps could contain private information. Perhaps you can tell me what to look for in kgdb instead.
