From: Rich Wales To: bug-followup@FreeBSD.org Cc: freebsd@jdc.parodius.com Subject: Re: i386/103435: Kernel appears somewhat deadlocked during heavy ATA I/O (post-August 4th) Date: Sun, 01 Oct 2006 22:01:50 -0700 Following up on my earlier comments: I seem to be able to reproduce the problem reliably by running two concurrent "dd" commands (copying data from each of my two SATA drives to /dev/null simultaneously), and waiting a few minutes. Reading off just one of the drives wasn't enough to generate any timeout warnings, but reading from both at the same time apparently did the trick. Rich Wales richw@richw.org http://www.richw.org
