1996-09-02Detect stuck interrupts in the scc (if DIAGNOSTIC) and log it.briggs
Patches from Bill Studenmund <wrstuden@loki.stanford.edu>.
1996-09-01From scottr@netbsd.org:briggs
After servicing an interrupt, check to see that there's not another one pending before we clear the interrupt flag. This avoids a condition where the line appears to go catatonic (which is particularly easily triggered by pppd). From Bill Studenmund <wrstuden@loki.stanford.edu>. XXX - we should probably log this if it gets excessive.
