"wifi0: interrupt delivery does not seem to work"

[Chip Salzenberg]

Version 0.3.9 under kernel 2.6.12 works fine.

Version 0.4.4-kernel included with kernel 2.6.14 does not work, nor
does version 0.4.1 compiled separately; there seems to be a problem
with interrupt delivery.  As long as the module is installed,
keystrokes and all other interrupt-driven activity pause for a LONG
time.  In fact, often keystrokes will auto-repeat as the interrupt for
the key-raise event gets delayed.

C'mon guys, anybody have a clue here?  Anybody?  I'd like to use the
2.6.14 kernel, but hostap is holding back the upgrade.
