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.
