It's because the recent ymfpci driver tries to request_firmware() at first. And since no files are found, it just waits for certain time. A workaround is to install the firmware files from alsa-firmware 1.0.14rc* package. I'll fix the codes on 2.6.22 not to make external firmwares mandatory via Kconfig option.
