network interface card to use for a laptop 8.0 regression: consecutive panics (iwi / wlan / zfs ?)  
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

... 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 ... While I do not currently use ZFS, the wireless NIC I have been using most often for the last several months has been iwi0 on my laptop, on which I track stable/6, stable/7, stable/8, and head on a daily basis. While I have seen the interface bounce dwn & up repeatedly, and it refuses to communicate with an Apple Airport AP (while working with a _link_sys WAP11) under head (but the Airport is OK for stable/6 and stable/7; not sure about stable/8), it has been (at least) several weeks since my last panic, so I am inclined to suggest that iwi(4) and wlan(4) are unlikely to be involved in the root cause of the panic. Peace, david

While I do not currently use ZFS, the wireless NIC I have been using most often for the last several months has been iwi0 on my laptop, on which I track stable/6, stable/7, stable/8, and head on a daily basis. While I have seen the interface bounce dwn&  up repeatedly, and it refuses to communicate with an Apple Airport AP (while working with a _link_sys WAP11) under head (but the Airport is OK for stable/6 and stable/7; not sure about stable/8), it has been (at least) several weeks since my last panic, so I am inclined to suggest that iwi(4) and wlan(4) are unlikely to be involved in the root cause of the panic. Well, the panic points at iwi (see my screenshot pls). And there are other wifi regressions I've already noticed. On 6.x I had 2 issues with iwi: Interface was changing down and up especially when signal was weaker. And there was the dreaded scan stuck.  Sometimes the only help was to reboot the machine. On 8.0 I haven't noticed scan stuck and down&up happens a lot less.  But I guess this is due to newer iwi firmware (3.1 vs 3.0). On the other hand wireless interface is too slow to associate during boot and I'm seeing connection errors from e.g. ntpd. Also the following began appearing in the system log: kernel: iwi0: need multicast update callback And there have been other issues posted to the lists in last weeks. I'd love these to be fixed and I'm willing to help investigate. Regards, Martin PS:  I had the same panic today.  After reboot I kept losing connection after short time.  Restarting AP didn't help.  I switched laptop off&on and it's running happily since (uptime 10h).  Really weird. _______________________________________________ This e-mail address is being protected from spam bots, you need JavaScript enabled to view it mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to This e-mail address is being protected from spam bots, you need JavaScript enabled to view it

The ZFS messages in question get printed when ZFS initialises (in your case, when the kernel module was loaded). How or why it got loaded is beyond me. In this case would help to post these kinds of kernel messages taken directly from /var/log/messages instead of from dmesg

Wooden Nokia Nokia's Eco-Team, a group of workers developing a more environmentally friendly phone concept, designed the wooden kamerofon with 8 megapixel camera. Embedded in a wooden casing for Nokia looks quite rustic, and although difficult to actually call it organic, could be an interesting alternative to traditional telephones. Phone is made of wood from forests with sustainable management, Polish Pottery Milano photo cars.motorization4u.co.uk which is obtained mainly from the spirit of eco (although it would be more environmentally friendly device made of bamboo for example).
