kernel panics on sio interrupt-level overflows

This problem had unusual solution. It seems the key to this problem is
that FreeBSD 5.3-STABLE-p5 (I have updated my system) has DEADLOCKS
when intensively using sio device on high speed (115200) with SMP support.
It seems that MPSAFE causes those deadlocks. Turning


in /boot/loader.conf
makes the system to work fine & stable instead of panicing every hour
or more often
