Comment(by werner):

 Matthias, I agree with the sentiment. That's also why I left the bug open
 so long, on the off chance that the bug would somehow show up again. But
 it
 didn't.

 The change that made it "disappear" is the complete replacement of the
 SDIO
 stack. That's some 10'000 lines of Atheros SDIO code that were removed
 from
 our kernel and now we're using something like the same amount of different
 code (the Linux SDIO stack) in its place.

 And yes, I had 2.6.28 running for weeks without seeing this problem, while
 it would quite reliably show up on 2.6.24.
