[Asterisk-Users] Zaptel module load errors under stock Fedora Core 2 (2.6.8-1.521 kernel )

[Adam Fineberg]

Just a reminder, if you are using the stock fedora kernel I'd recommend 
rebuilding it without preemption turned off as I've experience kernel 
panics from the zaptel driver.  Digium tech support agrees (or at least 
did a few weeks ago) that is was a problem.
