iwn crashing on 11n network
The issues is here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214435 We observed same error from two cards, Intel Centrino Wireless-N 1000 and Intel Centrino Ultimate-N 6300 both on 11. This card used to work in FreeBSD, where 11n is not supported, so it connects to an 11a network instead. Now it connects to nothing, even after -ht -- which will causes the whole system to reboot after lots of disconnects. -- Zhihao Yuan, ID lichray The best way to predict the future is to invent it. ___ ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
Intel I210 (igb) sometimes consume all CPU on not-so-big traffic — need help!
I still have problems with my E-1220v3 server equipped with Intel I210
adapter. It can not be loaded more than 100Mbit/s because it is
connection to internet.
But sometimes four interrupt threads "intr{irqXXX: igb0:que Y}" consume
100% CPU. Interrupt rate is very modest:
% vmstat -i
interrupt total rate
...
irq276: igb0:que 0 851899713 1193
irq277: igb0:que 1 907338150 1271
irq278: igb0:que 2 907538207 1271
irq279: igb0:que 3 768217584 1076
irq280: igb0:link 2 0
%
But CPU consumption is 90-100% per thread:
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND
11 root -92- 0K 544K CPU2 2 146:22 98.30% intr{irq278:
igb0:que 2}
11 root -92- 0K 544K WAIT 0 178:18 81.55% intr{irq276:
igb0:que 0}
11 root -92- 0K 544K WAIT 1 135:34 77.77% intr{irq277:
igb0:que 1}
11 root -92- 0K 544K CPU3 3 138:57 67.50% intr{irq279:
igb0:que 3}
procstat -ak looks suspicious:
% sudo procstat -ak | grep igb0:que

Is device polling enabled?
