[Xenomai-help] Problem running xeno-test, koan on PowerBook

Hi

Yesterday I compiled xeno trunk (revision 240) for my Powerbook.
Using the 2.6.13 kernel I only did some early boot messages the last one was 
"openpic: exit".

Using the 2.6.14 kernel I had no problem starting up and using it for a couple 
of hours. (I am writing this email with it.)

The diff in the configs concerning xenomai is the following for the 2.6.14 I 
choose the selected skins (native, uvm, rtdm, vxworks) as modules and for the 
2.6.13 everything as built in.

The I switch to root and did the following:
export  LD_LIBRARY_PATH=/usr/xenomai/lib
modprobe xeno_native
modprobe xeno_uvm
./koan
Xenomai/uvm: real-time nucleus v2.1 (Surfing With The Alien) loaded.

The latency/switch test gave the following results:
ng:/usr/xenomai/testsuite/latency# ./latency
== Sampling period: 100 us
RTT|  00:00:01
RTH|-----lat min|-----lat avg|-----lat max|-overrun|----lat best|---lat worst
RTD|       -7541|       -7052|        1030|       0|       -7541|        1030
<..>
RTS|       -7758|       -7052|        1139|       0|    00:00:09/00:00:09
ng:/usr/xenomai/testsuite/switch# ./switch
== Sampling period: 100 us
== Do not interrupt this program
RTH|     lat min|     lat avg|     lat max|        lost
RTD|        2387|        2441|        9928|           0

Then I tried running xeno-info which did run fine (see attachment)

I got into problems running xeno-test as it managed to shutdown my system 
three times. The first time while running cat /proc/looadavg, the second time
while "running quietly for 10 seconds" and the third time very early.

What is wrong with my tests?

Any hints would be appreciated.

For the record, a while ago I also tried 2.6.13+ipipe on my powerbook. 
Got an early hang like you. Didn't care to investigate further. Maybe, 
it just doesn't work, but who cares when there's 2.6.14 :-)
