Stephen,
Debian received this bug report on sky2:

Does this sound like a plausible symptom of the bugs fixed by:
f6815077e75c5b7f55b56fc3788e328514d4e72a sky2: fix transmit DMA map leakage
3fbd9187d004149fb8a98c9cb51ef9f4a4f66aca sky2: hand receive DMA mapping failures
In any case, are the above suitable for 2.6.32-stable (once merged by
Linus)?
Ben.
