Request for help to identify some bugs (part two)

Good evening again,

As I already wrote on this list [1], I have a problem with KDE 3.4.2 on my
ibook. When I insert a cdrom, kded (in fact the "media watcher" part of
kded) starts eating all the cpu and I have to eject the cd using de F11

This problem have been reported in the Ubuntu BTS under the number 10193.

In this list, Johannes Raspe reported [3] about another problem with kded
that he solved setting hdc to udma1 [4] but this leaded to other problems
(hdc: lost interrupts) [5].

I don"t have the same problem as Johannes (kded crashing when exiting KDE)
but I tested setting hdc to udma1. With this, kded no longer eats cpu but
hald is stuck with the cdrom (ide-pmac lost interrupt, dma status: 8080 ;
hdc: lost interrupt ; hdc: status error: status=0x58 { DriveReady
SeekComplete DataRequest } ; ide: failed opcode was: unknown ; hdc: drive
not ready for command) and the cdrom is unusable ; I have to kill hald to
be able to eject the cd.

May this problem (the first one described in this message) be related to
dma, knowing that outside of KDE everything's ok?

Without touching to hdparm, /dev/hdc is set to mdma2. What should be the
correct mode for an ibook?
