The following reply was made to PR kern/177536; it has been noted by GNATS. From: Martin Birgmeier <Martin.Birgmeier@aon.at> To: Andriy Gapon <avg@FreeBSD.org> Cc: bug-followup@FreeBSD.org Subject: Re: kern/177536: zfs livelock (deadlock) with high write-to-disk load Date: Tue, 02 Apr 2013 20:07:05 +0200 Thanks for the pointer - which I knew about, but unfortunately found out too late that the kernel needs to be compiled with options STACK and/or options DDB/KDB for this to work. Could this information be added to that page? I already recompiled the kernel, but are ambivalent about whether I should now hope to see the deadlock again... ;-) One more thing: Could you point me to the SVN revision in head and/or stable/9 which presumably contains the (partial) fix?
