FreeBSD freeze

After update few weeks ago freebsd began to freeze from time to time. Can't find any reason in logs or other way. System may halt after an hour of work, or may work few days. Before halt it may respond to shell commands very-very slow....

MB: MSI P45 NEO3-FR. BIOS ATA configured as AHCI. JMicron ATA controller is disabled.
