XO becomes unresponsive

[Mikus Grinbergs]

Disclaimer:  I am not asking for help - I can just reboot and 
continue with my work.  This information is posted so that if anyone 
else runs into a similar situation, they might realize that they are 
not alone in seeing it.  [I have not tried to create this situation 
deliberately, so I do not know how repeatable it is.]


Running ~cjb/fedora-xo/20090416.img (installed via 'copy-nand'). 
This is a heavily customized system, using a swap partition on an SD 
card.  [It also has an USB hub, with USB devices plugged into that.]

Was running a 'find' command (in Terminal) against the principal 
partition of the SD card.  Noticed that the XO became unresponsive. 
Went to the text console (ctl-alt-F2) and tried to log in.  That, 
too, didn't go - because the XO never completed the login.

In the meantime, every four or so seconds (i.e., periodically) the 
following group of 9 text lines was being output on the text console

   olpc-ec: running cmd 0x15
   olpc-ec: received 0x33
   olpc-ec: running cmd 0x15
   olpc-ec: received 0x33
   olpc-ec: running cmd 0x15
   olpc-ec: received 0x33
   olpc-ec: running cmd 0x10
   olpc-ec: received 0x55
   olpc-ec: received 0x2a

The last of those lines kept changing from group to group.  I saw 
values of 0x30,0x2e, 0x32, 0x28, 0x26, 0x34, 0x34, 0x2e, 0x32, 0x2a, 
0x2c, 0x2e, ox28, etc., etc. in that last line.


None of this meant anything to me - as I said, I just rebooted.

Note:  I typically experience unresponsiveness on F11-on-XO sooner 
or later (often during a 'find' [which I use heavily]).  The 
unresponsiveness seems to come on sooner with Soas2 run from an USB 
stick - then I do not have a swap partition "active".
