[Xenomai-help] testsuite/clocktest hangs

Hi all,
  I am running some tests on my mpc5200b board running Xenomai 2.4.5 with
kernel DENX-2.6.25. When I run the clocktest program, it hangs after a
variable period of time. Xenomai's watchdog recognizes it as a runaway task,
and gdb tells that thread 1 is hanging at nanosleep(). Same behaviour with
DENX-2.6.26

Here's the output of gdb:

Program received signal SIGINT, Interrupt.
[Switching to Thread 0x48024d90 (LWP 352)]
0x0fe1ebb8 in nanosleep () from /lib/libc.so.6
(gdb) thread 1
[Switching to thread 1 (Thread 0x48024d90 (LWP 352))]#0  0x0fe1ebb8 in
nanosleep () from /lib/libc.so.6
(gdb) bt
#0  0x0fe1ebb8 in nanosleep () from /lib/libc.so.6
#1  0x0fe4bea0 in usleep () from /lib/libc.so.6
#2  0x1000259c in main (argc=1, argv=0xbfa6eb84) at clocktest.c:243
(gdb)

Thank you

Giammarco

Could you try latest clocktest.c from SVN (2.4.x or trunk)? I fixed a
very similar issue recently, but I'm not sure if it applies to your
scenario.
