Hmmm ... EBADF is returned by ioctl() to indicate that the passed fd is not 
valid (DIOCGIFSPEED returns EINVAL to indicate error) so that means that 
somehow the reference to "/dev/pf" got scrabbled or was never setup correctly 
(which would be strange when everything else works).

If you are familiar with gdb, you could try to set a breakpoint in 
"eval_pfaltq()" and check if pf->dev is a properly initialized fd or not.

Other than that, I can only invite you (and everybody else) to check out 
-current. Not only does it provide newer, better pf- and altq-support, you 
will also help to shake out the last bunch of bugs in order to make 5.3 a 
success. Thanks!
