[linux-dvb] unknown v4l symbols from dmesg on reboot

Allan,
          the other thing you could try would be to do an lsmod before 
you reload and direct the output into a file. Do the same after the 
reload and then do a diff on the two files. This should show if there 
are modules being loaded the first time but not the second. Perhaps 
there is a rule somewhere that is loading something.

BTW Gentoo is brilliant for keeping up with the latest kernel, that is 
one thing I miss having moved to Ubuntu. I chose Gentoo to bootstrap my 
knowledge but after a while I stopped learning and then it began getting 
in the way:-P

Cheers Paul
