This bug is extremely difficult to pin down. I cannot reproduce it at
will. The system has to be up for a long time, which is difficult with
testing the late RC's of 2.6.30 and the code in wireless-testing so
that new bugs don't end up in 2.6.31-RCX. That said, it still was in
2.6.30-RC6 and I'm not aware of any changes since that would fix it.

My operating kernel is patched with additional diagnostics to help me
understand why a kmalloc request for a buffer of 1390 bytes suddenly
ends up as an O(1) request. Unfortunately, I don't have any answers.
