      I use my Qube 2 as a wireless router (among other things) and 
before 2.0 it used to crash silently with no message and no core every 
week or so.  Putting the adapter into promiscuous mode always crashed it 
after only a few hours.  I never investigated much, but the crashes only 
happened when the Prism-2.5-based wireless adapter was installed and up. 
  I tried several -currents, but the crashes always happened.  I wanted 
to file a pr, but I couldn't narrow down the problem.

      As soon as I upgraded to 2.0 the crashes stopped altogether:

  7:49PM  up 17 days,  6:35, 1 user, load averages: 0.11, 0.14, 0.09

      My Qube hasn't had a single crash since upgrading.  (It also 
hasn't had any file corruption problems even though I serve MP3's from it.)

      The LCD driver is great.  Mine shows the condition of my wireless 

while sleep 5;
do wiconfig wi0 |
awk '/Comms/ { printf("q=%d, s=%d, n=%d", $4, $5, $6) }

/Current channel/ { printf("c=%d, ", $4) }' > /dev/lcd;

      Solid as a rock, but blue and with a little green light on the front.

      I know this is bad, but I just built the 2.0 kernel, rebooted, and 
unpax'd 2.0 over the -current I was running.  I've been meaning to go 
back and do a neater job, but I haven't yet.  No harm done, it appears.

      I recommend it, but what do I know?
