I reported the problem with 2.1.110 last week, and Ingo sent me a
patch that made it do the looping you describe (if you wait the system
eventually recovers after sptting out about 30 of these lines). I told
him the patch made things worse.
I don't understand why this patch was then included into the kernel
:-(
