Hi guys,
I am recompiling the 2.6.34 cyanogen kernel in order to activate the ertm experimental feature in l2cap layer. I copy the config file from the Nexus One with CM6 installed in order to build a identical kernel but with ertm activated.
I am using fastboot to load the new kernel.
Everything goes well but the new kernel is unable to complete the process of loading the bcm4329.ko module. Executing lsmod says:
bcm4329 238095 1 - Loading 0xbf000000
Trying to insmod manually the module:
<4>[ 138.772552] dhd_module_init: sdio_register_driver timeout
I have the same problem with a HTC Magic and the wlan.ko module.
<6>[ 145.241790] TIWLAN: Driver loading
...
<6>[ 148.025421] TIWLAN: Driver initialized (rc 0)
...
but the loading of the driver is not finished and ...
# lsmod
wlan 773871 1 - Loading 0xbf000000
It seems something in the loading module chain is failing. Any tip about that?
Thank you!

Did you push the kernel modules (that were built automatically with the kernel) to your phone?

Yes, indeed, I have used the new kernel (the one I have compiled) modules with the all working kernel (the one which comes with cyanogen 6.0rc1 ROM), and they work. So the problem is not with the modules, but with the kernel system for loading modules.

Correct me if I am wrong, but I thought erfm could be enabled via the /sys-interface, even on stock kernel?!

Hmmm, it could be. You can activate it using a module param when you load the module if you have l2cap as a module, so maybe you can do that. I am not 100% sure about that.
Finally I have created a boot.img and flash it and the kernel now works perfectly with the modules and the wifi is working. So it seems that using "fastboot boot kernel" is not as robust as flashing the kernel.
