All -
I am attempting to connect the Intel 6250 using a Raspberry Pi ARM box and am having some issues. I natively compiled the wimax-tools, open source supplicant and wimax stack on the Pi without fault but when I connect (right after the TLS handshake) the box hard locks on a kernel panic. The entire message reads as follows:
skb_over_panic: text:bf0237f8 len:272 put: 272 head:cc8afa00 data:ca8affa20 tail:0xcc8afb30 end:0xcc8afb20 dev: wmx0
I tried to strace wimaxcu while trying to connect in the hopes that it would give me some insight into the issue but it really didn't:

lsmod shows the proper drivers:

i2400m 88760 1 i2400m_usb
wimax 18192 1 i2400m
I've considered recompiling the kernel natively on the Pi but I doubt that would have any effect. Does anyone have any suggestions as to what can be done to resolve this? It should be noted that I'm using a Mini-PCI-e to USB adapter on a 2A USB hub but I have tested this setup on an x86 system and it ran flawlessly.
