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 Linksys 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.
