Re: [parisc-linux] Trouble booting a 710 (bushmaster)

[Christoph Plattner <christoph.plattner@dot.at>]

I have the same SCSI message on my 720. The problem here
is definitly only one device, the TEAC floppy on the
SCSI bus. When I disconnect it, it runs perfect.

So this message also shows problems with special devices.
I don't know, if there are incaptibilities in the devices
(under HP sometimes this drive is seen as boot device, some
times not....).

Ot there is a problem in the routine probing the devices ....

With friendly regards
