X-BeenThere: freebsd-stable@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Production branch of FreeBSD source code List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 04 Jan 2010 15:23:58 -0000 Hallo, A few hours ago I experienced 3 consecutive panics on this freshly installed 8.0, the last panic just 28s into boot sequence. It seems to me that culprit could be iwi/wlan possibly with help from zfs or others. More details even with screen-shot of the last panic follow. I have used versions 5.3 to 6.4 on this laptop, the last one being the most stable and smooth. A few weeks ago I moved to 8.0 (fresh install) and since then I've been experiencing funny issues. Last night I was writing an email when I noticed my wi-fi link was gone. I checked /var/log/messages and saw the following: wlan0: link state changed to DOWN wlan0: link state changed to UP wlan0: link state changed to DOWN wlan0: link state changed to UP wlan0: link state changed to DOWN wlan0: link state changed to UP linux: pid 6189 (skype): syscall inotify_init not implemented ZFS NOTICE: Prefetch is disabled by default on i386 -- to enable, add "vfs.zfs.prefetch_disable=0" to /boot/loader.conf. ZFS WARNING: Recommended minimum kmem_size is 512MB; expect unstable behavior. Consider tuning vm.kmem_size and vm.kmem_size_max in /boot/loader.conf. ZFS filesystem version 13 ZFS storage pool version 13 While wifi weirdness did not impressed me, I was perplexed by ZFS messages. I checked kldstat and indeed ZFS was loaded. Note that I have not attached any ZFS storage devices nor I have ever configured ZFS on this laptop. And before I could investigate any further my laptop froze and then rebooted. After reboot I logged into X11 and was checking system logs while waiting for background fsck to finish. I noticed that wifi was screwed up, probably reset did not reinitialize it properly and the driver was at lost. And as soon as fsck finished the system suddenly rebooted. And it was getting worse. Next reboot did not even finish and the system panicked again. At least this time I could see a message and so I took a picture of it for your perusal: http://mato.gamato.org/freebsd/aw1n/2010-01-04_05-59-10_panic-8.0-iwi.jpg FreeBSD mb-aw1n-bsd 8.0-RELEASE FreeBSD 8.0-RELEASE #0: Sat Nov 21 15:48:17 UTC 2009 root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386 Please note that this is just one of multiple issues I'm having since moving from 6.4 to 8.0 and now I'm even worrying about my data etc. :( What else would you need from me to investigate further please ?
