linux 2.6.9-rc3: ub oops on device removal

[Soeren Sonnenburg]

Hi,
I get this oops on kernel 2.6.9-rc3 on a 15" powerbook.

xmon trace screenshot is at:

Any ideas ?

First you need to use -rc3-mm2 (it has some fixes), and then
add the appended patch which fixes your problem specifically.
The ub in 2.6.9-rc3 is not useable without these fixes.
