A few hours ago I experienced 3 consecutive panics on this freshly

to me that culprit could be iwi/wlan possibly with help from zfs or

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.

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.
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 -- the file in
question is handled by syslog and will have timestamps.
I can't help with the rest of the problems mentioned, sorry. :-(
There's nothing else in log regarding ZFS. It sure was loaded as I
checked with kldstat. But I have not loaded it nor I have ever had any
device with ZFS on it near this laptop. Really strange.
This appeared in log shortly before a crash:
Jan 4 04:42:24 mb-aw1n-bsd kernel: wlan0: ieee80211_new_state_locked:
pending SCAN -> AUTH transition lost
Jan 4 04:42:24 mb-aw1n-bsd kernel: wlan0: link state changed to UP
Jan 4 04:42:24 mb-aw1n-bsd kernel: iwi0: firmware error
And then again on subsequent boot. Wi-fi did not work and system
panicked again. Then panicked already during boot. A then I switched
it off which obviously helped (to restore HW to its defaults?).
Hm..
