Under heavy >write loads this leads to a system crash. The problem here is the system crash, not that the table starts out your drive with a tag count of 255. CAM should automatically reduce the count to the maximum supported by the device. Can you give some details about the panic you are seeing? -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
