From: matt To: freebsd-current@freebsd.org Content-Type: text/plain; charset=ISO-8859-1 X-Content-Filtered-By: Mailman/MimeDel 2.1.14 X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 21 Feb 2013 06:43:34 -0000 I was testing a patch on r246300 or so, and wanted to see if it would apply cleanly to a newer copy of HEAD. Well it did, except I had a hang at boot, shortly after ZFS version and the last scsi devices appear. This easily could have been related to the patch I was testing, so I wiped /usr/src/ and /usr/obj (after booting kernel.old) and rebuilt world and kernel cleanly. I assumed that would resolve the issue, but it did not. The hang happens right after zfs is announced, and the last da devices (some of which are usb) are reported. It comes before the noisy output of mps. Hang is complete, and single user or verbose don't yield much. I'm having trouble exfiltrating a dmesg from it, but it may be unrelated to the userland issues reported earlier, as single user does not resolve it for me. The svn up was at 11:20 pacific (GMT +8). Anyone else seeing similar issues? Hardware is an LSI mps device, "9210" crossflashed m1015. Pool is a zfs mirror. Works fine booting from r246300 kernel. Motherboard is an AMD Tyan. Pulling USB headers off the board didn't resolve it. Matt
