Ok so the bug originates form the fact that the driver is not in initrd? I'm far from a kernel developper, so what could my next step be? -Do you have enough information for now, (ergo, I do nothing)? -Should I re-file this bug with the initrd guys? -Should I file a bug that the kernel Makefile default settings are not up to par (since 'make install' creates the initrd image)? -Or should I do something else?
