I applied your patch. dmesg if PIN13 is open (wire disconnected on minipci adapter): b43legacy-phy4: Broadcom 4306 WLAN found b43legacy-phy4 debug: Found PHY: Analog 1, Type 2, Revision 1 b43legacy-phy4 debug: Found Radio: Manuf 0x17F, Version 0x2050, Revision 2 b43legacy-phy4 debug: Radio initialized b43legacy-phy4 debug: DebugFS (CONFIG_DEBUG_FS) not enabled in kernel config phy4: Selected rate control algorithm 'minstrel' udev: renamed network interface wlan0 to wlan2 Broadcom 43xx-legacy driver loaded [ Features: PLID, Firmware-ID: FW10 ] b43legacy ssb0:0: firmware: requesting b43legacy/ucode4.fw b43legacy ssb0:0: firmware: requesting b43legacy/pcm4.fw b43legacy ssb0:0: firmware: requesting b43legacy/b0g0initvals2.fw b43legacy-phy4: Loading firmware version 0x127, patch level 14 (2005-04-18 02:36:27) b43legacy-phy4 debug: Chip initialized b43legacy-phy4 debug: 30-bit DMA initialized Registered led device: b43legacy-phy4::tx Registered led device: b43legacy-phy4::rx Registered led device: b43legacy-phy4::radio b43legacy: phy rev < 3: RADIO_ENAB_LO 0xFD71 b43legacy: RADIO_ENAB_HI 0x40 b43legacy-phy4 debug: Wireless interface started b43legacy-phy4 debug: Adding Interface type 2 dmesg if PIN13 is connected (no modifications on minipci adapter): b43legacy-phy2: Broadcom 4306 WLAN found b43legacy-phy2 debug: Found PHY: Analog 1, Type 2, Revision 1 b43legacy-phy2 debug: Found Radio: Manuf 0x17F, Version 0x2050, Revision 2 b43legacy-phy2 debug: Radio initialized b43legacy-phy2 debug: DebugFS (CONFIG_DEBUG_FS) not enabled in kernel config phy2: Selected rate control algorithm 'minstrel' Broadcom 43xx-legacy driver loaded [ Features: PLID, Firmware-ID: FW10 ] udev: renamed network interface wlan0 to wlan1 b43legacy ssb0:0: firmware: requesting b43legacy/ucode4.fw b43legacy ssb0:0: firmware: requesting b43legacy/pcm4.fw b43legacy ssb0:0: firmware: requesting b43legacy/b0g0initvals2.fw b43legacy-phy2: Loading firmware version 0x127, patch level 14 (2005-04-18 02:36:27) b43legacy-phy2 debug: Chip initialized b43legacy-phy2 debug: 30-bit DMA initialized Registered led device: b43legacy-phy2::tx Registered led device: b43legacy-phy2::rx Registered led device: b43legacy-phy2::radio b43legacy: phy rev < 3: RADIO_ENAB_LO 0xDD71 b43legacy: RADIO_ENAB_HI 0x10001 b43legacy-phy2 debug: Wireless interface started b43legacy-phy2 debug: Adding Interface type 2 wow, there are many different bits ... >Are these related to large packets?

I'll try the driver version of b43legacy in kernel source 2.6.31.6. Perhaps it is not good to have bleeding edge :-) Thanks, Daniel _______________________________________________ Bcm43xx-dev mailing list [email protected] https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
