mixer_hwvol_init: delete locking, the only consumer seems to
be the ess driver and it only call it a creation time, I

crashes that had sn0 as the irq that's being serviced, when there was
no sn0 in the system. This seems to prevent them. Also, we want to
wait until after we've registered with the network layer before we
turn on the interrupt spigot to avoid races.

Fix a done list handling bug which exhibits under high shared
interrupt rate and bus traffic. As the interrupt register is
read after checking hcca_done_head, there was a small chance
of dropping a done list. Ignore OHCI_WDH interrupt bit if
hcca_done_head is zero so that OHCI_WDH is processed later.

o When we're resetting the board, make sure that we error out the pending
CCBs first. Otherwise the aha_cmd won't accept further commands, such
as those that are used to reset the card (AOP_INITIALIZE_MBOX). This
appears to cause a cascade failure where no more commands are possible
to the card.
o Reduce from 10s down to 1s the amount of time we're willing to tolerate
the card being awol. This helps the above case.
o Add some error checking to two commands issued in the probe.

PALM_4 initialisation hack. I've not confirmed it myself, but
seeing as we already don't use it for the Sony Clie_41, let's drop
it from the Clie_40 also and see what happens.
(Question: What about the Clie_S360 and Clie_NX60 devices? Do we
need to drop Palm4 from those as well? Possibly, but I've not had
any reports about those so I don't know.)

the problems with network MPSAFEty have been sorted out this will
be removed and the driver will default to MPSAFE.
We put them directly onto the free list instead of calling the
external mbuf free routine (that routine would have cleaned the flag).
This fixes a bug which manifests itself in falsely reporting a lot of used

operating mode to HostAP, the card will lock up indefinitely (but
the wi(4) driver can recover if you eject the card). The problem is
that the card needs to be "reset" in a way before you even change the
media to hostap. In practice this isn't as noticeable because you
probably do some operation beforehand which prevents the lock-up
before you enable hostap mode.
e.g.:
"ifconfig wi0 up media autoselect mediaopt hostap" will lock up
(if you just inserted the card).
"ifconfig wi0 up ssid foo media autoselect mediaopt hostap" won't lock up.

couple of ethernet cards that have appeared recently on ebay. Silicom

these cards, but I thought I'd get the device into pccarddevs.

GEOM was not designed to handle changing the sectorsize
