# SMP kernel config file options:

# Optional (built-in defaults will work in most cases):

>Description:
When the system is running the SMP kernel, more than a buffer full of
sound will cause the sytem to lock up. If running X, the cursor
stops moving and ctrl-alt-del, ctlr-alt-bs fails to free the system.
If fdformat /dev/rfd0.1440 is attempted, 3 to 5 Vs are printed and then
the system locks up hard. It requires a hardware reset to break the
system free.
The same actions running a UP will work fine. The UP configuration file
is the same as the SMP configuration file with the exception that the
UP has the SMP options commented out.
