[parisc-linux] Booting 712 with CD 0.5

[Arnaud.ATOCH@oecd.org]

Thanks for the enlightment.

Should I try a new CD-ROM or should I wait untill next ISO image is created
?
IS the shutdown also due to this bug ?

The bug is real. A driver is calling pci_map_single() and pci_unmap_single()
without specifying which direction the DMA is going. Cache flushing on 712
(PCXL) systems needs to know. I'll assume it's the SCSI driver since
it looks like we are talking to a SCSI CD-ROM.
