This is a multi-part message in MIME format. --------------020505080100030203010700 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit 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! -- Niclas --------------020505080100030203010700 Content-Type: application/octet-stream; name="panic.out" Content-Transfer-Encoding: base64 Content-Disposition: attachment;
