Oh right, CONFIG_BLK_DEV_FD dunnit! I wonder how I came to include it, since
I usually start with pmac_defconfig and from that only remove stuff I don't
need, except for few things like the USB drivers. It boots, however, and
I even got the SUN12x22 font to work now, thank you!
What's still causing problems is the DMA code, however. There's still the

: hda: Enabling MultiWord DMA 2
: hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
: hdc: packet command error: error=0x54
: ATAPI device hdc:
:   Error: Illegal request -- (Sense key=0x05)
:   Invalid field in command packet -- (asc=0x24, ascq=0x00)
:   The failed "Start Stop Unit" packet command was:
:   "1b 00 00 00 03 00 00 00 00 00 00 00 "
: cdrom: open failed.

error on startup. I can't see if this is directly causing any problems, but
the performance for hdc is frequently down to 0.8 MB/s. Apparently ejecting
and reloading the disk is sufficient to bring it back to 1.6 MB/s, but after
returning from sleep it's down again (this is the 24X CD-ROM on a 333 MHz
PB 101, FYI). Well, at least I found an easy workaround now...

I also noticed that power consumption during sleep had dramatically increased
with the previous 2.2.15pre kernels; I'm currently checking out if that problem
persists.

Thanks again,
							Derek
