[linux-dvb] Duel Hauppauge HVR-1600

Thanks Andy for the reply.

I did what you said and now I'm getting an memory error message when booting

The message reads:
Initrd extends beyond end of memory (0x37fef23a > 0x30000000)

I tried lowering the amount but anything over 128M and I get the error

Here is my config file:
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img

You're out of vmalloc address space.  Each cx18 needs 64 MB of vmalloc
space for MMIO mappings.

Do this:

$ cat /proc/meminfo | grep Vmalloc

Edit your bootloader's config file to add a 'vmalloc=xxxM' option to
your kernel commandline.  Use a value that is 128M greater than your
current VmallocTotal.
