I appreciate your response. Being new, I did not have dumpdev set in rc.conf, and my root device is ZFS, which I snapshot before the upgrade and I completely rolled back after rebooting, before looking for any dumps. If I attempt the upgrade again, I have dumpdev configured now, and I will not rollback /var/crash after rebooting.

I am running a GENERIC amd64 kernel, which I have not compiled. Is there a way to deduce the appropriate line without a dump? Or, would I need to trigger a panic in another machine running the same kernel?

I do not have any out-of-tree kernel modules installed. The ones I have (in my running 9.1 system) are:
1 23 0xffffffff80200000 1323780 kernel
2 1 0xffffffff81524000 2084f8 zfs.ko
3 2 0xffffffff8172d000 5c68 opensolaris.ko
4 1 0xffffffff81735000 4a30 aesni.ko
5 4 0xffffffff8173a000 2b4a8 crypto.ko
6 3 0xffffffff81766000 dde0 zlib.ko
7 1 0xffffffff81774000 4cd0 cryptodev.ko
8 1 0xffffffff81779000 5a958 ipl.ko
9 1 0xffffffff81a12000 15c2 fdescfs.ko
10 1 0xffffffff81a14000 bfda pefs.ko
Cheers,
