[Bug kprobes/5759] probes in sched.c on preempt kernel cause reboot


------- Additional Comments From jkenisto at us dot ibm dot com  2008-02-13 18:08 -------
Created an attachment (id=2259)
 --> (http://sourceware.org/bugzilla/attachment.cgi?id=2259&action=view)
header file used by probe.c

Updated header so __init functions are commented out and joined with previous
lines, so that line number = array index + 1.

I probed all non-__init functions in kernel/sched.h.  Probing any of the
following functions causes a hang:
- add_preempt_count
- preempt_schedule
- sub_preempt_count
If I omit these (and the __init functions) from func_array.h, rebuild probe.ko,
and run "insmod probe.ko first=0 last=210" (i.e., probe all the other functions
together), everything seems to be fine.
