With some kernel's configuration there is such messages in dmesg in different places while using kprobes.
I investigated this and founded that it reproduced with https://gist.github.com/azat/7078890#file-config-3-12-0-rc5-deb And not reproduced with https://gist.github.com/azat/7078890#file-config-3-12-0-rc5-worked-kprobe I used the next script for testing https://gist.github.com/azat/7078890#file-ktap-sh Here is the initial email log with Jovi (ktap author): http://www.freelists.org/post/ktap/BUG-unable-to-handle-kernel-paging-request-after-ktap-script-to-trace-SyS-write If I can help, please let me know!
