This looks like a problem that has been fixed. You can perform a renego for FAST-40 after boot (using camcontrol) with the kernel you are using, but updating the driver files to lastest ones should fix the problem: You just have to replace src/sys/dev/sym/* by the latest driver files from RELENG4 or HEAD and rebuild your kernel. You may let me know if this actually fixes the problem. Regards, G=E9rard.
