 today i updated my b4 to the latest firmware, then installed ship-2 via
 usb, then olpc-updated to the latest joyride build that i could find.

 [the impetus for the updates, today, beyond the RTC bug, was that the
 wireless on the B4 didn't seem to want to come on.  Empty neighborhood
 screen, etc.  There were some libertas error messages in the dmesg output,
 which were initially somewhat concerning.  Now, I wish that I'd written
 them down.  Oops.]

 a minute ago my ubuntu laptop (an aging dell inspiron 8200, with 802.11b
 truemobile mini-pci card, running 2.6.22...) started spewing error
 messages and the card began frequently resetting itself.  LOTS of spewage.

 turning the b4 off seems to have eliminated the issue.  huh.  :-)
 possible complicating factors:

 My local network has a BUNCH of 802.11g devices on it.  A d-link pci card,
 several different belkin and linksys usb dongles, etc.  All talking to the
 one AP.  And there are several, several, several APs RF-visible from here-
 typically 20-30, depending on which window of the house you happen to be
 closest to.

 There's also a B2-1 here, running 406.15, with very non-current-ish
 firmware on it.

 the AP to which the laptop and the B4 were both connected is a Netgear
 WGR614v6, running firmware V2.0.13_1.0.13NA.  The B2-1 was disconnected
 and at a point where it would have liked for me to type in a WEP key.

 The AP is WEP, as there are several devices that don't do WPA and still
 need to work.

 This sounds a little bit like the reported WDS/frame/mesh scenarios that
 I've seen mentioned on a couple of occasions recently... but not exactly.

 I am happy to do further testing - and endure further possible crashes of
 my non-XO laptop - to help get this stable again.  :-)
