I read the boot log slightly differently - I'm assuming that the boot log is from the kernel which _will_ be kexec'd from, so we don't yet know whether the patches work or not. I looked at the oops, and it's in tasklet_action, but for some reason the unwinder is unable to unwind and provide a backtrace, so it's not very debuggable. However, this is a useful backtrace for me in a different way: to provide to people who want to deprecate the frame-pointer based backtracing to prove why the unwinder based solution still isn't up to the job. -- RMK's Patch system: http://www.arm.linux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
