Thanks. I did so, but this does not help. When I does not work even
after 20 secs it fails to mount. After a lot of boot attempts I have the
following picture:

1. It always mounts fine when verbose message is selected.

2. It mounts fine when the line below about 'umass0:1:0: Attached to ... ' is
   printed, if it is not, the mount fails later after 20 secs waiting;
   
here is a working boot:
