Comment(by Quozl):

 Replying to [comment:12 Quozl]:
 > (The difference between today and yesterday is the presence of an ad-hoc
 network formed between a WRT54 and an XO-1).

 Upon further testing, the symptom still occurred with the ad-hoc network
 absent (the AP and the XO-1 fully powered off).  That excludes the network
 as a contributing cause.

 The symptom (the BUG at if_sdio_interrupt+0x3f7/0x7ca [libertas_sdio]) is
 solidly reproducible here, five out of five tries on two particular
 laptops, using only "boot, then wait" with os64.

 These two laptops are XO-1.5 B2 with cardboard tag SD PWR ECO and SER PORT
 JUMPER.  The symptom occurs with or without the serial cable to the
 logging host being connected.

 The other two XO-1.5 B2 without serial port are not reproducing this
 symptom.
