Hi, I was wondering if anybody has experienced a hang of the entire OS when profiling the functions of the kernel module. In other words, when I run the following script probe kernel.function("*@kernel/*.c").return{ printf("%s %s", threadindent(-1),probefunc()); } the entire OS gets stuck. I also tried with probe kernel.function("*@kernel/*sched.c").return{ printf("%s %s", threadindent(-1),probefunc()); } and after some printing the OS gets stuck again.
I'm using systemtap v1.4 and kernel 2.6.24 on Gentoo. Thank
