grepping for irq on the boot log I cannot find same irqs (apart for
the two 255).

Could it be a problem that the only HDD is at ata3-master and nothing
at ata2 ? (ata0, ata1 not present - why ever - me doesn't know that
much about sparcs yet).

Or does this sound to sparc specific so that I should ask for
clarification on sparc64@ ? Cc: and Reply-To: set.
