Hi all!

I still do have problems with using my IDE controller with parisc-linux. =
I=20
get the following message onto my console when generation large traffic t=
o /=20
from my IDE disks:
hp-c240:~# dd if=3D/dev/ide/host0/bus0/target0/lun0/disc of=3D/dev/null
Dino f2000000: IRQ base 96, stuck IRQ lines? 0x2
Dino f2000000: IRQ base 96, stuck IRQ lines? 0x2
Dino f2000000: IRQ base 96, stuck IRQ lines? 0x2
[...]
The device using the IRQ 96 is the internal ethernet controller (not the =
IDE=20
controller!):
hp-c240:~# cat /proc/interrupts | grep 96
 96:      17424            Dino  eth0

Seems that there is still nobody else who tried to use cheap IDE disks wi=
th a=20
parisc machine :-(

For those who are interrested anyway: The reason that causes the kernel c=
rash=20
is the multimode option. You can either select it for native IDE support=20
(CONFIG_IDEDISK_MULTI_MODE=3Dy) or it is automatically selected with the=20
special drivers for i.e. Promise controllers.

Regards
Joerg
