Ben Hutchings says:

====================
Fix regressions introduced by the last set of fixes (sorry):

1. Potential deadlock when disabling TX queues.
2. RX was broken on architectures other than x86 and powerpc.

I still expect to send one more bug fix for 3.9, but as it sometimes
takes days to reproduce the bug it's going to take a couple of weeks of
testing to be confident that it's really fixed.
