Physics crash on shutdown

[carrott]

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).

backtrace from gdb

Sorry, haven't been able to pick anything useful out of the backtrace. Closing as 'not sugar', but do reopen if you can reproduce it. Could well have been a crash due to the USB stick corruption as you mention.
