I had a panic and got a dump for amd64 head -r329465 . I was able to use /usr/libexec/kgdb to look at the vmcore.* file. But my prior attempt to use /usr/local/bin/kgdb failed:

ABI doesn't support a vmcore target (kgdb) It seems that for amd64 /usr/local/bin/kgdb is still necessary. (I normally deal with powerpc64 and powerpc for kgdb use, odd contexts in the first place. I did not know of the amd64 issue before this.) === Mark Millard marklmi at yahoo.com ( markmi at dsl-only.net is going away in 2018-Feb, late) _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
