SDIO probe: Error -84

[Simon Twogood]

Dan, I believe I'm using firmware version 8.108.3p2, could that be  
correct? This line shows up in syslog when the card works:

    libertas: 00:19:88:05:11:34, fw 8.108.3p2, cap 0x00000393

After loading with debug info I have been able to get the card working  
every time, so I can't reproduce the same error code for logging at  
the moment... funny how it always works that way.

I'll double check that my adapter card isn't flaky and try again once  
I'm done. If I get the same error code, I'll post the debug output.


Thanks,
Simon
