Upon its release, 11.2(11)P on a 7206 was so bad for us we had to back 
out of it within minutes of installing it. Cpu was pegged at 99%.

The source of that may have just been discovered yesterday in 11.2(12)P
(and 11.2(11.3)P) and was probably happening in 11.2(11)P and earlier.

SHO ALIGN showed millions of misaligned memory references. 
The trace led to frame relay compression code.

Even turning ALL F/R compression off still had the problem because
the code path was still there until the next reload.

This is now CSCds87720. The port with the problem is on a PA-8T.

FWIW F/R compression runs well in 11.2(12)P on a 4700M.

WFQ has also been a source of grief in recent 11.2 7200 code - just
turn it off.

And one can't go back far at all in 11.2 space with PA-2H Rev-B cards
that are only just being supported.
