There have been several patches around "fixing" one-shot interrupt URBs
lately. With the help of David Brownell, I've made a "fixed" version of
the fix and included it in the PowerMac stable tree (2.4.20-ben3). I'm
about to push it to the main PPC bk trees as well.
For those interested, here I copied it below. Depending on the feedback
I get about this patch, I'll back it out or submit it for inclusion
in Marcelo's official tree.
