Hi,

  Ive been using the kprobes on X86 m/c and found the following problem with
the following kprobe and the testsuite.

1. A probe is placed for the sys_gettimeofday with the pre/post/fault handlers
   defined (k-test.c is attached).

2. The nptl01 test from the ltp testuite is executed and the system gets into an
infinite loop (nptl01.c is attached).

Ive attached the log file that contains the output that was seen when
the above test is performed (kprobe-nptl.log), the log file is
stripped for the purpose of attaching.

Please provide me some information regarding the above failure.
