Hello Konstantin, I did some research regarding the kernel crash with the following results>
1) Last working kernel is: "FreeBSD 11.3-BETA1 (BLNN719X) #8 r348361: Wed Jul 3 09:30:17 CEST 2019" 1a) DDB-Backtrace of the crashing kernel r348362 can be seen on "Boot_BT.jpg" in the dropbox directory "https://www.dropbox.com/sh/buzxekimo2h2r67/AADpUvLndhm2SHa5t9s9Ckksa?dl=0" 2) Source code revision is: root@blnn719x - /usr/src 2056 # svn info Path: .

There were absolutely no changes in the stable/11 in the area of SMP startup for quite long time. To get anywhere, you should perhaps add ddb to your kernel configuration and get the backtrace. The backtrace would be long, I am only interested in the first several frames before faults go into recursion. But, since 1 month earlier kernel worked, and there were no changes, this might indicate either a failing hardware (your machine is quite old, it is Core2 Xeon, am I right ?) or problems with your build environment. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
