Charger code? I tried a kernel without charger code, and no luck, rmmod fails the same way. dmesg says: [ 111.093078] wlan0: authenticated [ 111.097442] wlan0: associate with 06:27:22:f9:10:6a (try 1/3) [ 111.104553] wlan0: RX AssocResp from 06:27:22:f9:10:6a (capab=0x421 status=0 aid=2) [ 111.104705] wlan0: AP has invalid WMM params (AIFSN=1 for ACI 2), will use 2 [ 111.104736] wlan0: AP has invalid WMM params (AIFSN=1 for ACI 3), will use 2 [ 111.256652] wlan0: associated [ 184.681427] HS USB OTG: no transceiver configured [ 184.681488] musb-hdrc musb-hdrc.0.auto: musb_init_controller failed with status -517 [ 184.681976] HS USB OTG: no transceiver configured [ 184.682006] musb-hdrc musb-hdrc.0.auto: musb_init_controller failed with status -517 [ 187.690338] twl4030_usb 48070000.i2c:twl@48:twl4030-usb: Initialized TWL4030 USB module [ 187.698303] musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) [ 187.698333] musb-hdrc: MHDRC RTL version 1.400 [ 187.698333] musb-hdrc: setup fifo_mode 4 [ 187.698394] musb-hdrc: 28/31 max ep, 16384/16384 memory pavel@n900:/my/tui/ofone$ Best regards, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
