F11: kernel/boot hangs at creating initial device nodes with 2.6.30-rc6

[Pasi Kärkkäinen <pasik iki fi>]

Hello.

Yesterday I installed latest F11/rawhide. The default installed kernel
(2.6.29 something) works fine. 

I compiled custom 2.6.30-rc6 kernel, and created initrd for it, and tried
booting it. 

Booting process gets stuck at "creating initial device nodes". 

Any ideas? I assume that's during initrd execution.. 
Something missing from my kernel config? 

Any tips would be appreciated. 
Thanks!
