Since today's update to Kernel:HEAD kernel-desktop-3.0.rc2-1.1, I get the following in syslog every ~3 seconds:
[ 2967.744144] cfg80211: Calling CRDA to update world regulatory domain [ 2967.752126] cfg80211: World regulatory domain updated:

The crda is triggered via udev [1]. Maybe to turn the cfg80211 debug on [2] could reveal why the action repeated. [1] /lib/udev/rules.d/85-regulatory.rules:KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/crda" [2] config CFG80211_REG_DEBUG bool "cfg80211 regulatory debugging" depends on CFG80211 default n ---help--- You can enable this if you want to debug regulatory changes.

The changes in iwlwifi also don't look like they could have anything to do with this issue. I'll keep an eye on it, to see if it reappears after the next update to a properly built suse kernel :-) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
