Hi Inaky,
? Since many of us are having problems getting the card's WiMax functionality to work in kernels >= 2.6.30 I have started to?explore exactly where things went wrong in the driver code.? I am new to this type of work but thus far I have gotten a cluged version of 2.6.29.6 code to compile in my 2.6.31.2 build environment (before it would fail whenever I tried running 'make').? However, I am now seeing kernel crashes having to do with "i2400m_dev_bootstrap" whenever I insert the card.? I have included my error message below for your reference:
