Hi Rolf,

Did the machine worked with the old debian kernels?

According to http://hwdb.parisc-linux.org/view.php?type=machine&name=705 
it has a PA7000 (PCX-S)) CPU, which is PA1.1a generation.
Probably we still use some assembly which is not supported on PA1.1a yet.
My "oldest" testmachine was a 715/64 which is PA7100LC aka PA 1.1d 
generation...

I can try to look into this, but this will take some time since I'll 
leave for two-week vacation shortly...

Helge
