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

[Rob Emanuele]

In the source RPM this is from the i686 non-SMP config:

# CONFIG_PREEMPT is not set
CONFIG_PREEMPT_VOLUNTARY=y
# CONFIG_PREEMPT_NORESCHED is not set

It looks off except for the voluntary case (what ever that means).
