chan is an index variable, used to loop over a list of channels, and here it is used _after_ the loop, in which case it doesn't point to a DMA channel struct anymore. Dereferencing it leads to a corruption of a random memory location, which in my case was a pointer inside a clock struct. Fix it by using a local variable pointing to the DMA device.

Guys, this was a _real_ bad joke, cost me almost a day, and that patch has been reviewed by two persons...
<rant>
So far 2.6.29(-next) has been very bad for me, regressions all over the place, lots of wasted time hunting them down:-(
