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.

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,
