Comment 8 for bug 106957

Miek, it is possible that this is a systemtap or kernel problem
(in which case we'd appreciate hearing more details about the
crash - see http://sourceware.org/systemtap/wiki/HowToReportBugs).

But it is also possible that your rebuilt kernel does not exactly
match the one you're *running*. This situation is sometimes
hard to catch in software, though we plan to improve on this.

It is also possible that the ubuntu snapshot of systemtap is
too old - many bugs have certainly been fixed in the last six
months.
