hi,
just for the record:

I've got the same crash as Albrecht in Sept. with 2.2.18pre4-ben1
and linuxppc2k on my PB3400 without the wakebay app.

Sep 18 00:35:03 apple kernel: Kernel panic: kernel access of bad area pc c00cf34c lr c00cfa88 address 24 tsk
+pmud/297

System.map-2.2.18pre4-ben1:
c00cf218 t idepmac_sleep_device
c00cf334 t idepmac_wake_device
c00cf400 t idepmac_sleep_interface
c00cf4e4 t idepmac_wake_interface
c00cf728 t idepmac_notify_sleep
c00cfab0 T ide_dma_intr
c00cfb8c T ide_build_dmatable

My only solution was to snooze without the cd module.

In the meantime I switched to potato; with the current

15:28@pts/2 ~ > uname -a
Linux apple 2.2.18pre17-ben1 #38 Wed Oct 25 18:51:51 CEST 2000 ppc unknown

now it's something special, that I realized today. A snooze and prompt
wakeup with the cd module inserted seems to hang the entire machine,
but it waits for dma'ing /dev/hdc.
This can last up to _four_ minutes, and I have to wait 'cause nothing
can be written to hda. 
The message 'system awake again' appears after hdc knows
and reports its dma status.
