Subject: mac80211: NOHZ: local_softirq_pending 08
Date: Fri, 11 Sep 2009 16:48:49 +0200 [thread overview]
Message-ID: <200909111648.50902.mb@bu3sch.de> (raw)
Hi,
mac80211 (or some other part of the networking stack) triggers this warning
in the NOHZ code:
NOHZ: local_softirq_pending 08
08 seems to be NET_RX_SOFTIRQ.
It happens, because my test driver b43 handles all RX and TX-status callbacks in
process context. I guess some part of the networking stack expects RX to be in
tasklet and/or softirq context.
We also have a report of this warning in wl1251, so it's probably not a b43 problem.

Greetings, Michael.
