[Soekris] Reboot stop in monitor on specific CF Card brand

[Nick Hibma]

After booting FreeBSD 6-STABLE succesfully, typing in reboot leads 
eventually to a prompt from the monitor. Cold boots always succeed, warm 
boots (reboot) always fail (even when you type in reboot on the monitor 
prompt).

and the OS boots fine!

This problem keeps on reoccurring on various flash cards and is annoying as 
there seems to be no reliable way of knowing which cards work. We've had 
problems with SanDisk cards starting to report read/write problems requiring 
a reboot of the OS. That made us switch to Kingston, but now the second 
batch of cards produces problems on reboot (multiple CF cards, ~ 5 
installed).
