Hi, I've tried to build and install kernel 3.0. The standard Ubuntu configuration worked very well. But after I ran 'make localmodconfig', rebuilt and rebooted my wireless didn't work. After some investigation I've found that option CONFIG_WIRELESS_EXT is no longer set in .config file. But no matter how I tried to include it in .config file it was automatically deleted by 'make oldconfig' and again kernel compiled without it. Then I've found that if I include in the build some (completely unnecessary to me) wireless module which has 'select WIRELESS_EXT' in its Kconfig then it stays in .config file and resulting kernel works very well with my WiFi network. In fact even if I add 'select WIRELESS_EXT' to Kconfig of the driver for my wireless card (ath9k) everything works as well. I'd think that such behavior is a bug, although I don't know on which side. Either on the side of wireless drivers which all have to have 'select WIRELESS_EXT' in their Kconfig files or on the side of kbuild system which doesn't allow me to set CONFIG_WIRELESS_EXT unless some driver requires it. Interestingly enough requiring WIRELESS_EXT works only with drivers, because I've tried to add CONFIG_LIBIPW (it requires WIRELESS_EXT too) but it was automatically deleted from .config file along with CONFIG_WIRELESS_EXT. So I couldn't include only this library. Could you tell me if this is indeed a bug or am I missing something here? I'm not subscribed to the lists so please add me in CC.
