Hi!
I consistently get this panic while trying to boot a kernel build from
r243530. It happens when the entropy harvesting rc.d script starts.
r243380 worked fine, I haven't tested any revisions in between.
Attached is the backtrace from the kernel, as gotten by kgdb. The
machine uses zfs as a root pool, and there have been churn in this area.
To my untrained eyes, however, the issue seem related to hdaa.c.
Please let me know if I can provide any more information.
Regards!
