Please Help! Can anyone tell me why U9 is oscillating? Obviously the LTC6244 is unity gain stable (see U7, U10). The oscillation frequency is about 1.2MHz. The simulation time-step is 10ns.

LTspice schematic:

(in case you are wondering: L2 is the secondary inductance of a 1:1 transformer. The "K" statement for that and the primary are not captured in the screenshot.)

PS: I've now solved it.
