That looks like the race condition on ttys (remember the one that caused some of the rocketport fun). Im not sure when Ted put the fix back into the 1.3.x -> 2.0 code for generic tty drivers
The standard problem here is that you have more than one device file in /dev referring to a pty using both the old major number #4 and the new major numbers (#2 and #3). This causes the debugging code to screw up, since it doesn't realize that a tty could be opened from two different sets of (major,minor) numbers.
