It seemed to fix the problem for me as well.
In principle looking at the logs it looks more like a userspace bugs
due to threading functions.

Does panalosa has the patched kernel (same one as the one on peri) ?
The protection ID traps shouldn't happen any longer, and from the buildd
logs on peri it does seem like that the ProtID traps don't happen there.

I think this bug is unrelated to the ruby1.9 issue.
