We've seen one case now where on a specific x86 platform some new changes instroduced on 2.6.32 rounded up the PCI memory area incorrectly and had an impact on devices like sky and ath9k. For more information please see: http://bugzilla.kernel.org/show_bug.cgi?id=14402 There is a fix for this now available and in Linus' tree. But -- wrt160nl doesn't run x86 :) I take it, so... lets see. > i use openwrt trunk, with compat wireless from 3.11.2009. is the device > broken? if not how to tell, how do debug? You want to enable debugging as I explained to the user on the bug report above. In the bug report you can find the same exact situation and how I explain to get more information to further debug this issue. Please post your dmesg logs once you get debugging enabled, and enable it completely and load. Compat-wireless could use a fix for ./scripts/driver-select ath9k to enable ath9k debugging, but I haven't gotten around to it yet so for now please just compile all the drivers. Luis
