Ejecting a firewire iPod causes kernel panic

[Chris Halse Rogers]

Trying to eject the ipod results in a kernel panic.

I have a 3G iPod, connected via firewire.
Up-to-date Breezy install, kernel version 2.6.12-8-amd64-k8

Running the command "eject -v ipod" from a terminal results in:
eject -v ipod
...
unmounting /media/ipod
/dev/sdb2 is multipartition device.
Trying to eject /dev/sdb2 using CD-ROM eject command
Kernel Panic - not synching: PCI-DMA: High address but no IOMMU

Running "sudo umount /media/ipod" succeeds, but the ipod still reports "Do not
disconnect"

Ejecting when the ipod is connected via USB works:
eject -v ipod
...
unmounting /media/ipod
/dev/sdb2 is multipartition device.
Trying to eject /dev/sdb2 using CD-ROM eject command
CD-ROM eject command succeeded

Not sure if this is an ieee1394 bug, or an amd64 bug. Do you have an i386 system
to test this on?

Tested on the same computer using the latest Breezy i386 live cd - Ejecting
works fine there, so it seems to be something amd64 specific.
Anything else I can do to help?

I can confirm this bug. Kernel panics giving out this message:

"Kernel panic - not syncing: PCI-DMA: high address but no IOMMU"
