Does the stack-trace change every time?

Most of the time I get nothing, and when I get something it is mostly
scrolled out already (there is only so much you can put in 80x25).  I
had to hack the kernel to reduce the output to the bare minimum.

There were couple more fixes on top of it. Is it included in your kernel already?

They are all in 7.2-rc1 already.
