* 2.6.29 works perfectly.
* 2.6.30-rc3 (includes my patch) does work as well, but I see quite often those messages:
hda: command error: status=0x51 { DriveReady SeekComplete Error }
hda: command error: error=0x54 <3>{ AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown
* drivers/parisc/superio.c had no (important) changes between 2.6.29 and 2.6.30-rcX
* to me it seems your changes to drivers/ide/ns87415.c have raised those problems.
* maybe you added some inb() in the new paths, which should call superio_ide_inb()
(see to of ns87415.c) instead?
* it seems the problem happens more often in some fault-paths, for example when
reading a faulty disc in the cdrom drive
