Yes; other things wrt "debug kernel" ... options DDB options GDB options KDB options KDB_TRACE #options KDB_UNATTENDED options INVARIANT options INVARIANT_SUPPORT options WITNESS #options WITNESS_KDB options WITNESS_SKIPSPIN > If so, remove that so you can find the real error.

Aye. After installing kernel with W*KDB option missing, FreeBSD 8 now runs meaningfully long enough before crash-reboot. Thanks Ian. I will now do binary search which is causing seemingly random crashes. Crashes seem to coincide with network traffic on wlan device (ath). Between Jun 2015 & Jul 23 2015, only changes relevant are apparently related to TCP & openssh. > (IMO the spewage related to this makes >witness >essentially useless.) Is there any point then in keeping even plain WITNESS option? -- _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
