are doing. Other than that, there likely isn't anything that you need to do for 'locking' in 4.x. The kernel is non-reentrant there, so you don't need to worry about synchronizing multiple threads.
thanx a bunch, scott. it's been a nightmare trying to debug the driver and to try to find out why the driver compiled from the same source tree works on freebsd 5.x and doesnt work at all on freebsd 4.x . so far, i've been gloriously unsuccesful at this, and am getting at my wits end on what to go look at.
the userland application uses pthreads, and works like a charm both on 4.x and 5.x without using the device. however, when the device is used, it somehow has synchronization errors on 4.x, leading to timers (created in the userland app) timing out and the like.
