Hi!

My N900 can boot kernel from v3.12-rc5-n900 branch compiled with 
arch/arm/configs/rx51_defconfig. Also it can boot full Maemo5 
system (with CSSU and some minor system changes) and usb network 
via g_nokia.ko gadget working fine...

So if it does not working for you then kernel usb subsystem could 
have problems with using gadgets directly from zimage.

After some hand-bisecting and real-bisecting, I found two commits that
cause problems for 3.13: With these reverted, I get usb networking
back in 3.13 on nokia n900.

(Pali, if you revert these, you should get working usb networking in
your 3.13 branch, too.)

Any ideas?

Hmm maybe check if current stable kernels work for you without
reverting anything ? Few weeks ago I did the the following two fixes
with cc stable v3.13+:

96be39ab34b7 usb: phy: twl4030-usb: Fix regressions to runtime PM on omaps
85601b8d81e2 usb: phy: twl4030-usb: Fix lost interrupts after ID pin goes down

I tried these on top of 3.14 (where my revert fixes stuff) and no, it
does not seem to help. (Trying stable would be a bit more work).

Do you want me to try on 3.13, too?
