Readers,
Can anyone explain if the following 'dmesg' outputs are useful to understand why after start of X session, the wireless driver fails sometimes? The wireless driver does not start automatically and is always started manually with the command (as root):
modprobe b43
Below is the dmesg output when the command above, starts successfully the wireless driver:
b44: Broadcom 44xx/47xx 10/100 PCI ethernet driver version 2.0 b44 ssb1:0 eth0: Broadcom 44xx/47xx 10/100 PCI ethernet driver ...

Below when the 'modprobe b43' fails to start the wireless driver:
b43-phy0: Broadcom 4311 WLAN found (core revision 10) b43-phy0: Found PHY: Analog 4, Type 2 (G), Revision 8 b43-phy0 ERROR: FOUND UNSUPPORTED RADIO (Manuf 0xFFF, ID 0xFFFF, Revision 15, Version 0) b43: probe of ssb0:0 failed with error -95 Broadcom 43xx driver loaded [ Features: PNLS ]
The only solution seems to be to switch off the computer and start again, sometimes 3 or 4 times repeated failure occurs.
