We've also seen issues with 12.2 mainline with ISDN+PPP (this is in
C7200 land w/PA-MC-2E1-120s, serving ISDN clients of various flavours).
12.2(12a) seems to have the least problems sofar with various vendors/OS
mixes on the client end.  The problems we saw were evident as PPP LCP
negotiation failures in debugs (someone else showed a familiar looking
debug about a month or two back).  

In early 12.2 (various trains) there's an "input Q wedging" on multilink
PPP member interfaces bug to look out for, also (notice 'full' interface
input queues on your B-channel interfaces), dont have the ID handy
though.
