2315	Physics crash on shutdown	carrott	garycmartin	"I started up sugar on a stick Mirabelle to test out a new branch of USB sticks. I fooled around with physics for a bit, stopped phyics and tried to shut it down. It refused to shutdown and acted rather strangely. Looking in the logs, I found mention of an abort.

I have the abort and coredump, and attached is a backtrace from the core. If you want the core, I can attach too (it's about 4.5MB compressed).

To get gdb I had to transfer the sugar on a stick into virtualbox using vboxmanage as my laptop's wireless is not supported. During the gdb and debuginfo installation process the guest locked up with 100% cpu usage in the host. I have a snapshot taken during this lockup time. On restarting the guest, I find that there is filesystem corruption. I cannot be 100% sure that the corruption stems from the crash and restart (sugar on a stick appears to be a linux filesystem on a vfat filesystem??) or from corruption on the usb stick (which might explain why it was behaving strangely in the first place).
