FireWire DVD-R ... a never ending story

FireWire DVD-R ... a never ending story

Hi,

I have got a Laptop and attached to it are three firewire devices, two
HDs and one DVD writer (last in chain).

Right now I am running 2.6.10-rc1-mm5 on a debian/unstable.

I started with this situation.

Laptop
  |
HD [on]
  |
HD [on]
  |
DVD-R [off]

I turn the DVD-R on, I start k3b, I can see & write dvd-Rs.

Something happnes (perhaps my dvd-r is broken), but I turned it off, and
on again and it doesn't get recognized again, more, all Firewire traffic
is blocked.

I reboot this time the dvd-r is on, but after the reboot the dvd-r
doesn't get recognized. So I turn it off. Reboot and afterwards turn it
on. It gets recognized.

Now I play around and turn it on and off a view times until this happend
[dmesg see below]. After this oops, no more access to the two other hard
disks.

I can't test the dvd-r anymore, because I think its broken (today just
crap is sold, two years old and its broken already!)
