Hello, 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 debug.mpsafenet="0" in /boot/loader.conf makes the system to work fine & stable instead of panicing every hour or more often -- Best regards, Oleg Tarasov mailto:subscriber@osk.com.ua
