Comment(by carrano):

 I am observing the XO (C1 - joyride 81 - q2d02 - 19.p0) that showed this
 behavior for the first time.

 The machine was running for 3 hours, without problems.

 I hit the "arp" command and got:

 {{{
 libertas: tx watch dog timeout
 }}}

 and then the arp table (which, btw displayed only one entry - the school
 server)

 (I have "1" in /sys/module/libertas/parameters/libertas_debug)

 And we get the hung. I cannot ping the school server, but the mesh traffic
 is still there (I hear it in the sniffer).

 But, in this case, iwpriv msh0 fwt_time won't respond.
 Another thing. This machine will answer to iwconfig quickly

 And here comes the interesting part. I cannot use a usb key on the
 machine.

 {{{
 usb1-2: device not accpeting address 7: error -110
 }}}

 I tried many usb devices keys. (though I could connect a keyboard)

 Are we facing a USB (hardware) related issue (at least in this machine) ?
 It seems we cannot talk to the radio. Could the arp command triggered it?
 The machines at KIM's office (on which MBletsas reported the above, are
 B4s).
