Unfortunately, we don't have a lot of visibility into that. The Intel folks will need to be involved. I'll copy Wey-yi and Johannes. Hopefully they can give this some attention. You might also open a bug at bugzilla.intellinuxwireless.org for their convenience. We've been getting a lot of complaints about iwlwifi stability in general lately. We may need to flood their inboxes until they can spare us some cycles... :-) > A workaround that makes the wifi bearable (but not pleasant) is: > > modprobe iwlwifi wd_disable=1 > > I can still see the failures, but at least it recovers: > > 64 bytes from 8.8.8.8: icmp_req=617 ttl=54 time=42.9 ms > 64 bytes from 8.8.8.8: icmp_req=618 ttl=54 time=46.1 ms > 64 bytes from 8.8.8.8: icmp_req=619 ttl=54 time=50.9 ms > 64 bytes from 8.8.8.8: icmp_req=620 ttl=54 time=46.3 ms > 64 bytes from 8.8.8.8: icmp_req=621 ttl=54 time=48.1 ms > 64 bytes from 8.8.8.8: icmp_req=622 ttl=54 time=41.4 ms > 64 bytes from 8.8.8.8: icmp_req=623 ttl=54 time=46.3 ms > 64 bytes from 8.8.8.8: icmp_req=625 ttl=54 time=2209 ms > 64 bytes from 8.8.8.8: icmp_req=626 ttl=54 time=1213 ms > 64 bytes from 8.8.8.8: icmp_req=627 ttl=54 time=213 ms > 64 bytes from 8.8.8.8: icmp_req=628 ttl=54 time=44.2 ms > 64 bytes from 8.8.8.8: icmp_req=629 ttl=54 time=43.3 ms > 64 bytes from 8.8.8.8: icmp_req=630 ttl=54 time=44.6 ms > 64 bytes from 8.8.8.8: icmp_req=631 ttl=54 time=45.0 ms > 64 bytes from 8.8.8.8: icmp_req=632 ttl=54 time=44.3 ms > 64 bytes from 8.8.8.8: icmp_req=633 ttl=54 time=44.0 ms > > I still get one of these lock ups every 10 to 30 seconds, > but at least I dont have to throw the hardware switch > back and forth on the laptop to recover. > > If there is more debug info I can get someone, let me know > > Paul > -- > devel mailing list > devel@xxxxxxxxxxxxxxxxxxxxxxx > https://admin.fedoraproject.org/mailman/listinfo/devel -- John W.
