[Voyage-linux] Max CF size for WRAPs/ALIX

[Kim-man 'Punky' TSE]

Edwin,

I don't know what exact way you formatted the disk, but did you try 
/usr/local/sbin/format-cf.sh to do so?  You may also try to disable DMA 
with ide=nodma in kernel parameters in the bootloader.

and what does "cat /proc/partitions" return?

Regards,
Punky
