Ok Petr, I've been trying for days to reproduce without any luck.

I had a look at your traces, and I'd like something else when it happens :
 1) The patch I provided earlier applied
 2) This done (the 'cat' after the bug) :
	mount -t debugfs none /sys/kernel/debug/
	cat /sys/kernel/debug/pxa-dma.0/channels/4/[sd]*

Cheers.
