 I upgraded my unsecured system (through copy-nand) from update1-703 to
 joyride-2181. When running "boot" it reflashed the firmware to q2e11 and
 then booted fine. I installed some activities, shut down, packed it up and
 went home.

 When I got home I tried to boot it and it just hangs with no output. If I
 hit esc and run "boot" manually it also hangs, with no output.

 Using the debugger I tracked this down to a seemingly infinite loop in
 scan-occupied inside the jffs2 driver.

 This may be a regression in q2e11, or maybe something funky happened
 during shutdown or on the journey home, I'm not sure. Here's the disk
 image which should allow you to reproduce:

 If helpful, I can wire up a serial console and provide you ssh access to a
 connected box so that you can diagnose on the affected system.
