Today I've been trying to work through the mess that is musb bring-up on recent kernels (v2.6.38). While I still haven't succeeded in getting a working gadget stack (modprobe g_ether fails with ENODEV), I've come across configuration where musb causes a link failure in 2.6.38 if built as a module:

MODPOST 249 modules
ERROR: "musb_read_fifo" [drivers/usb/musb/musb_hdrc.ko] undefined!

Configuration attached.

Cheers,

- Ben

musb can't be built as module, I sent a patch making it bool recently until we re-work those parts of the code.

I'm working on it. Hopefully none will be necessary as this is all the fault of incorrect configuration.

Ahh good, thanks for that change! This should eliminate at least one nasty failure mode.
