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.
