Narrative:

ZAU kept us high for traffic. When clear of traffic, ATC asked us to cross awsum at 10000 ft. When it became apparent we could not comply with our clearance, I advised ATC. At awsum ATC asked for our altitude. We were passing 10900 ft. No further report requests were requested from ATC.
