In order to find out why NetBSD hangs I booted the GENERIC kernel with =
DEBUG and DIAGNOSTIC options enabled.=20
The system halts almost immediately early in the booting. No clues what =
to do with this ....
Your comments are welcome

BTW I checked the machine and both scsi drives, battery, RAM and the =
rest is in good condition so this is not a sympton of a hardware failure =

If this is not obvious, I used serial line to attach to the machine (not =
even sure if hill stuff works at all and I have only one hp-hil keyboard =

which is a real precious thing these days)

The version of NetBSD I am writing about in all the three messages is a =
crosscompilation of 4.99.26 (make release) on a
i386 NetBSD 4.20. =20
