[Transformer TF300T Q&A, Help & Troubleshooting] tborg:
Wifi modules crashes at boot

Hi guys,

thanks for this great thread and all the work.

I tried to install the xubuntu to my tf300 tg running on CROMi-X 5.4; 4.2 bootloader.

I've tried almost everything described here (various kernels - 2.2.6, 2.2.9; various fs images - original post, 13.04, 14.04), but with the most I am unable to boot to the xubuntu at all (crashes during boot, xfce never goes up).

With the combination kernel v2.2.9 and filesystem from the original post I managed at least to boot xubuntu without wifi. But whenever I try to install the kernel modules (either from mod_update.zip or install.tar.gz) the boot starts crashing again. When I delete the content of /lib/modules, it is ok... without wifi of course.

So it must be something in the kernel modules. From /var/log/syslog it seems that something goes nuts in raw_ip_net. (see part of the log in the bottom)

In Android the mod_update patch worked perfectly and WiFi works.

Please, does anyone have any idea what I am missing or doing wrong?

I skimmed through the whole thread but it seems that nobody else had this problem (maybe except vikktorn, but no solution was posted), so I really don't know :(

Thanks for any help.
