Sometimes I get the behaviour above (which I trace to the first test in b43_write_initvals(). And sometimes I get this behaviour: pcmcia driver load: [ 102.850000] ssb: Sonics Silicon Backplane found on PCMCIA device pcmcia0.0 [ 102.880000] b43-phy0: Broadcom 4318 WLAN found (core revision 9) [ 102.990000] b43-phy0 debug: Found PHY: Analog 3, Type 2, Revision 7 [ 103.010000] b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2050, Revision 8 [ 105.610000] phy0: Selected rate control algorithm 'minstrel' [ 105.650000] Broadcom 43xx driver loaded [ Features: M, Firmware-ID: FW13 ] First ifconfig wlan0 up (note it's trying to use the open firmware - which I don't have): [ 108.770000] b43 ssb0:0: firmware: requesting b43/ucode5.fw [ 108.910000] b43 ssb0:0: firmware: requesting b43/pcm5.fw [ 109.170000] b43 ssb0:0: firmware: requesting b43-open/ucode5.fw [ 109.330000] b43 ssb0:0: firmware: requesting b43-open/pcm5.fw [ 109.520000] b43 ssb0:0: firmware: requesting b43-open/b0g0initvals5.fw [ 109.690000] b43-phy0 ERROR: Firmware file "b43/pcm5.fw" format error.
