Re: uClinux Source Code Patch (Again) for Dual PC Modem

Has anyone had success creating a working kernel besides Bruce?
I attempted to compile one on a debian box, using the actiontec provided
toolchain and source plus Bruce's patch.  I am able to compile the
binary but when I boot up something goes wrong as I can no longer talk
to the modem.  It is hard to tell how it is failing without the
daughterboard.  Bruce - would it be possible to post a copy of your
compiled kernel so I can try it out on my board?  If someone with a
daughter board feels like trying my kernel I'll put it here:

Thanks -john
