I upgraded a few months ago to 3.2-RELEASE, and, immediately started seeing problems with the Buslogic BT-958 controller. I would get the following messages, and then, the system would become unreachable across the network without a reboot, although the console still worked, and you could read disks locally. Strange. Anyway, I got busy, and rather than mess with it more, I decided to go with 3.4-RELEASE instead. Same messages, but, the behavior is better, because it seems to recover, and the system continues to work. Still, I'm concerned about it. The messages are about 6 busy mailbox messages: fred# Jan 25 02:06:48 fred /kernel: bt0: Encountered busy mailbox with 191 out of 192 commands active!!!
