Description Natrio 2012-01-23 05:40:46 UTC 
The "ymfpci" module conflicts with udev-177/178, which uses libkmod(kmod) instead of modprobe(module-init-tools), during loading firmware.

According to the "udev" developers,
> Some broken kernel drivers load firmware synchronously in the module init
> path and block modprobe until the firmware request is fulfilled.

> The modprobe-generated firmware request is a direct child device of the
> device which caused modprobe to run. Child device event are blocked until
> the parent device is handled. This dead-locks until the kernel firmware
> loading timeout of 60 seconds is reached."

The recent kernel should work as is because it now loads the firmware files directly.
