Hi,
I've just passed to udev from devfs (Gentoo daily sync with 2.6.12).

I've a problem with dvb drivers: after the modprobe it occurs about 10
seconds before udev creates the devices (/dev/adapter0/xxx), which it's
pretty unacceptable in a dining room settopbox.

With the same driver compiled with devfs this taked almost no time.
I discovered in dvb ML that it's a known problem and the suggestions are
to compile dvb in the kernel or to create the devices with a script
before loading the modules. 
I know that there are similar problems with other modules (see Gentoo
bugzilla with udev f.e.).

Now the question:
Do you know if it's a problem related with modules themselves or with
udevd or with udev design or what?
I checked that /sys/drivers/dvb/xxx seems ok as soon as the modules are
fully loaded (about 1 sec.).

So I wonder if I could use udevsend (or whatever) to create nodes
earlier, not a wonderful solution but better than create them with a
script.

TIA


Bye Uberto
