Hi,

I have installed version 2.4.6.1 of Xenomai with kernel 2.6.27.2
compiled for x86_64 on a Core2Duo Ubuntu 8.10 system. Having tried many
different options I still cannot get a system running that does not hang
when running xeno-test. I have disabled graphics (X) completely as I
thought it could be related, and this appears to stop the system
hanging, but if I generate some load, by e.g. doing a kernel compile in
another VT, the system hangs after a short time while running latency or
switches tests, and sometimes hangs anyway, always at a seemingly random
point during the test. Latencies themselves seem reasonable (max 10uS).

One thing: previously xeno-test was not running and instead displaying
'something died a xxxx or' (xxxx is a pid I believe) so I edited the
line 'if test 0 -eq $withBusybox ; then' to read 'if test 1 -eq
$withBusybox; then'. I am not sure if this has adverse effects? I saw
this same issue reported a couple of times in the mailing list, but not
resolved - advice was to read TROUBLESHOOTING which I have done and
tried several things to no avail.

The kernel is compiled with the following possibly relevant options:

Processor type & features
	SMP support enabled, 
	low latency pre-emption model enabled, 
	SMT (Hyperthreading) scheduler support disabled,
	Interrupt pipeline enabled,
Power
	Processor ACPI disabled,
	CPU frequency scaling disabled,
Real-time
	Interrupt shield support enabled
	Statistics collection enabled
	Watchdog support enabled
	SMI globally disabled (I am using an ICH7 chipset and wanted to
be sure this wasn't the problem)
	All interfaces/APIs enabled
	All drivers enabled

'dmesg | grep enom' looks reasonably normal as far as I can tell. I can
provide any logs, command outputs, kernel config or other details that
may be needed.

Thanks!

Ed
