Hi All,

The fs=0 unfortunately didn't solve anything, as to be expected because
I already had CDR_FIFOSIZE set to 0. I found some pointers in -bugs and
-current to kern_physio.c v1.23, but that didn't bring anything as well.

As a last resort I will reinstall 2.2.5 to see if that will help.

Thanks sofar, and keep me informed.

Greetings,
Walter
