Date: Wed, 04 Jul 2007 10:06:52 +0200 From: Jan Schmidle <freebsd-current@jschmidle.org> To: Current@FreeBSD.org Subject: Panic with areca and dd Message-ID: <468B551C.7070107@jschmidle.org>
next in thread | raw e-mail | index | archive | help
I reduced my Problem from zfs to a general disk, i/o problem.
But now i don't know if it is areca driver related or a
general freebsd-current problem.
When I start two dd's like "dd if=/dev/zero of=/dev/da1 bs=1024"
on different disks, the machine panics with the following backtrace and
stuff.
I also appended a complete dmesg before the crash. The machine is
running a cvsuped GENERIC
kernel from yesterday.
Does anybody know, how to solve this ?
