 From 3.4 - it was very slow - this is now probably fixed by your patches, but 
 i 
 already had the release done and tested with 3.2.
 
 For next release i plan 3.5 kernel.

My experiences with 3.5 include:

1/ The battery status sometimes doesn't read correctly and it reports '0'.
2/ Sometimes my sound playing program gets stuck waiting for the soundcard.
 This could be just be a problem with my program.
3/ The GPS auto-on-off didn't seem to work once.. which is odd as it works
 perfectly in all my testing.
 However my antenna seems to have problems as I cannot get a fix at all
 most time, though once I got one in 90 seconds.  Maybe I need to resolder
 something.

Not that I want to scare you off using it, but I always encourage testing,
and if you notice problem with any of these, you'll know it probably isn't
your faulty, and when you report it, that will increase my motivation to find
and fix the problem.

  There should have been some lines before that which are important.
  Possibly : omap_dma: You need to stop the DMA channels before unlinking
  or   : omap_dma: trying to unlink non linked channels
  
  Also, is this the 3.2 kernel?  I assume so.
 
 Yup. The whole dmesg is attached.

Thanks.  And indeed you did include all of the message that is relevant.
Which is very strange as there are two places in omap_dm_unlink_lch which do
a stack dump, and each has a 'printk' immediately before.

Thanks,
NeilBrown

Wow, so many changes, thanks Radek! I'm waiting for the GTA02 release to
perform some tests here.

Best regards,
