udev is too slow creating devices

[Giacomo A. Catenazzi]

Hello people!

When I load a module (with modprobe) the relative device is too
slowly created with udev, so modprobe return before the device
is really created. Because of this my init.d script will
fail with modular microcode + udev

test case:

udev + modular microcode:
$ modprobe -r microcode
$ modprobe microcode ; microcode_ctl -u
=> microcode_ctl does NOT find the device

$ modprobe -r microcode
$ modprobe microcode ; sleep 3; microcode_ctl -u
=> microcode_ctl FIND the device

[without udev it is OK, so I assume no errors
in modprobe]

Is it a bug of udev?
Else what workaround I can use? (sleep is to slow for
an already to sloow system initialitation)


ciao
