Description Josh Stone 2013-02-19 16:59:58 UTC 
Reported here: http://sourceware.org/ml/systemtap/2013-q1/msg00144.html

We have a limit of MAX_UNWIND_TABLE_SIZE for each of the eh/dwarf unwind tables, and binaries which exceed this are skipped.  However, it appears that the skipping is not quite complete, and can sometimes lead to a kernel panic.

The reporter confirmed that this commit solves the panic:
