[cross-posting for advice on general debugging + network-specific thoughts]
TLDR since a week or so, probably around r335381 I can reliably get my machine to hang*** by unloading pf, while there's network traffic (e.g. video streaming or rsync) and waiting a minute or two I still see it with r335576 a few times today. config & logs below, h/w is intel xeon v2667v4 on supermicro X10SRA-F dual igb nics. However each time there's no crashdump, & the usual ctrl-alt-esc does't work either. I'm a bit lost as to what I can do here to capture something useful. A few minutes later, the machine spontaneously reboots, I assume due to a h/w watchdog kicking up, and there is no crashdump info present in /var/crash/ as I'd normally expect. ***hang means simultaneously: - keyboard is unresponsive (capslock/numlock keys don't cause keyboard LEDs to toggle state) - control-alt-esc doesn't work to get to the debugger - music playing via mpd to an external USB DAC stops - network sessions & tap interfaces fail - X session contents freeze but remain visible Is there some way I can get a kernel dump even though the system has fully hung? - dmesg, rc.conf, ifconfig, sysctls etc https://git.io/f4HQZ - supermicro X10SRA-F bios v2.0a settings https://git.io/f4HQb A+ Dave _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
