Hi, I am new to gumstix and linux but i learned a lot by playing with gumstix. all i need for my gumstix project are wifi, usb otg as pheripheral and gpios. Everything is working but boot up time is just too slow and i think libertas_sdio and udev is taking lot of time. Currently, it takes about 3min to see wifi blue wifi led blinking from power on. I am using Overo air with tobi but eventaully will move to pinto-th. Kernel I am using is 3.0.0 + from sakoman and didn't change anything in .config file except usb otg. Any suggestion would be helpful.(what drivers i can remove from .config and scripts from rc#.d) below is a list of modules that i am using g_ether 35520 0 libertas_sdio 20338 1 libertas 92190 1 libertas_sdio cfg80211 161771 1 libertas lib80211 5435 1 libertas firmware_class more questions... I also tried to change .config file to remove some services that i can recognize and don't use, but again, kernel spends lot of time after this line "libertas_sdio: Copyright Pierre Ossman" and sometime, with reduced kernel, i get invalid format error when inserting module. I think either i messed up .config file or some step is missing. Do i have to compile modules every time i rebuild kernel by "#make modules" and "#make modules_install? then above modules are all i have to compile? it seems i can change that in "modules.builtin." am i correct? Thanks for reading this message.
