SOLVED kernel panic -- what information is helpful?

[pjc]

The latest beta kernel panicked my machine last night. I'm still in the kernel debugger, but don't want to reboot until I find out what information will help debug it. So far:

screenshot of the console (via IPMI)
"bt" and screenshot of the results

Is anything else helpful?

panic: solaris assert: 0 == dsl_dataset_hold_obj(dp, dsobj, ((char *)__func__), &ds) (0x0 == 0x2), file: /fusion/jkh/M/FN/FreeBSD/src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_scan.c, line: 1321

It's possible this is related to https://bugs.freenas.org/issues/6848 in some way, since this beta wouldn't mount all of the objsets in tank.

I think the screenshots and backtrace information is about all you could have submitted, and when the machine reboots it will also send this to our crashdump server if you didn't disable that in your preferences, so we'll have that too. Thanks for filing a bug report! That's very helpful.
