In the meantime I've managed to compile a custom kernel from Oct 17th
sources, but this kernel seems to have the same problem with netbooting as
the kernel from the 19980525 snapshot.

Please have a look at my console output:

Can anyoune tell me what is going on here? Unfortunately I can't save a

Perhaps I should mention, that there is no SCSI disk connected at the
moment. The SCSI plug inside is empty.

Any hints are appreciated.
