Wow you're the first person I've seen using a combination of T1 and E1 on the 
same card.  I wonder if this has something to do with it (i.e. a bug in the 
drivers).

I'm assuming you have the jumpers for span 3 and 4 closed in order to get E1 
operation on them (I doubt it would work this far without).

I would certainly be contacting Digium about this.  Span 4 being the only 
clock=1 should work just fine.

Just for fun, you might want to try putting span 1 as your E1 uplink, span 2 
as your E1 loopback, and span3 and 4 to your T1 channel banks.... Just for 
trying to sort this out (remember to adjust the jumpers if you do this).
