Two separate kprobes-related problems have demonstrated crashes
on recent fedoras (as well as on RHEL6, whence this bug was cloned).
The following patches should be applied active Fedora kernels.

linus commit 829e924                       Fix removed int3 checking order
https://patchwork.kernel.org/patch/108500/ Fix kprobes to skip prefixes correctly

Both of these affect x86.

I do not see this patch in any upstream git tree.

It is in mingo's tip/auto-latest.

Comment 3 Chuck Ebbert 2010-08-17 04:12:23 UTC
Commit 829e924 is in 2.6.34, which is in updates-testing for f13.

The other patch is upstream now as commit 567a9fd and is needed in 2.6.34 and 2.6.35 (f14).
