No, those are gone. But the new host reset routine gets called
endlessly. I added a printk at the very top of that function, and that
fills my terminal program's buffer in seconds.

The end result is the same: I still have this output:

libertas: 00:19:88:05:1c:53, fw 8.73.7p3, cap 0x00000393
libertas: Command 28 timed out
libertas: requeueing command 28 due to timeout (#1)

after that, it hangs.

Hmm, the 9263 should be able to handle sizes not modulo 4. But I'll
try, anyway.
