For what it's worth, I changed to CVS HEAD and the instability problems 
modprobe'ing the modules seem solved.  ifconfig down'ing an HDLC interface 
still produce a stack trace and a kernel thread hang, but it is at least 
sysreq sync'able.

My HDLC Abort problems are lessened, but not solved.  We haven't seen the 
problem in nearly five hours, reaching a new record.
