I rebooted a few hours after the previous comment (yesterday). Problem happened again today. Nothing known to be new in the environment. Kernel was 3.5.0-34 since June 14th and bug happened only starting June 29th, so it does not look like a kernel-level regression.

Could remarkably high solar activity ( source http:// www.ibtimes. com/solar- activity- cycle-peaks- 2013-more- solar-flares- expected- later-year- 1302041 ) cause unusual wifi interference that could broaden the scope of this bug to hardware/ environment that are usually unaffected ? ;-/
Anyway, a workaround is to turn off wifi and use wired network.
