Hello

Sorry for the delay
I found my problem of freeze, I tell it for information.

My X system (using gnome) is now stable.
The solution : I have desintalled gnome-power-manager

very thanks for your help

No you should use the right type for your procsesor.

I see that you are using X-window, so I guess you do not see the
console. Unfortunately, if your hang is due to a kernel oops we do not
have a clue. So, you should try and get the console output on another
machine, using preferably a serial cable, or if not possible the netconsole.

Re: [Xenomai-help] Problem of freeze

[John Yamokoski]

Greetings,

I have the same freezing problem after compiling/installing/running an
adeos patched kernel on an Ubuntu system. Unfortunately to uninstall
gnome-power-manager I must also uninstall 'ubuntu-desktop'.. which I
am not sure I want to do.

Any ideas? Do I need to switch to a different window manager? Is there
some setting with gnome-power-manager I can set that will avoid the
freezing?

I will also query the ubuntu community. If I hear anything back I will
post it here.

J.D.

Ok people. Please all stop thinking that you have the same problem as
Benoit. There are many ways to get freezes, it could be configuration
problems, irq sharing problems, adeos patch problems, drivers problems,
problems in real-time applications (such as infinite loop in a real-time
thread). So, stop jumping quickly to conclusions, do what we are asking
you, and provide feedback on your experiences.

Thanks for your reply
So now ACPI is enable and ACPI PROCESSOR Disable

I use xenomai with the patch adeos-ipipe-2.6.28.9-x86-2.2-07.patch from the Xenomai git

But i have the same problem :(

I have a question, when I configure the kernel, for the procesor type, can i use th right type for me (core 2) or I must use only 6x86MX type ?

Just to make you know that I'm (still) experimenting exactly the same
random freeze on Ubuntu Jaunty, with 2.6.28.9 kernel,
adeos-ipipe-2.6.28.9... patch and xenomai-git (but I think that does not
matter, since it seems a kernel issue!!)

I'll try to setup a netconsole environment as soon possible and let you
know what I can see in the kernel logs.

Dario

As usual, please send us /proc/interrupts, /proc/xenomai/irq, your
.config, and the version of the I-pipe patch you use.

Run the latency and switchtest tests, and tell us if you have the freeze
with them too.

Also, Benoit's problem was not in fact due to xenomai but to gnome power
management. This shows that the notion of "freeze" is very vague, and
without further information, we can not tell you more.

It has happened once during a test (latency I think), but I've also been
(next times, after reboot) able to run both of them without any issue.

Anyway, as soon as I reboot I'll run all the tests again.

I see... Well, of course, all is possible... I'm using
gnome-power-manager too, but while running plain Ubuntu kernel no freeze
happens, but... I mean... Who knows?!?!

I know, and I'm sorry of being able to be more specific since now. :-(
I'll test it deeper and let you know in detail.

For now, thanks a lot for your support! :-)

The point is not about blaming Gnome PM, but we do know for sure that
power management related drivers may have adverse effects on a
Xenomai-patched kernel - see the troubleshooting guide. If your kernel
enable those, and Gnome PM triggers actions on those such as CPU freq
governors, bad things may happen.

You .config will confirm or not whether this assumption is correct.

The problem could also be that gnome-power-management is trying to use
services from the kernel which are not available because power
management is disabled in kernel configuration.

[Xenomai-help] Problem of freeze

[btirefort]

Hello

I'am rookie in xenomai and i have a problem.

Here my configuration :

Linux base : CentOS v5.3 (with gnome)
kernel : linux-2.6.28.7
xenomai : 2.4.7
processor cpu familly  : 6
              type : 14 (Intel Core Duo T2500 2Ghz)
memory : 1 GB
HDD : SCSI with Adaptec AIC-7892B card

I have installed xenomai with no problem.
All options of ACPI, APM and CPU frequency scaling are disabled.

All seems to be good, but i have a problem :

Sometimes the system freeze, and i must reset the computer.
The system freeze sometimes during the connection to gnome (when gnome are enabling my desktop).
The system freeze also, when i am leaving the scrennsaver after a long period without using (after nigth for example).
The system freeze all the time when I try to launch netbeans program.

I don't understand why.

Can you help me please ?

Benoit

Please try adeos-ipipe-2.6.28.9-x86-2.2-07.patch from the Xenomai git
repository, it will probably fix you issue (in any case, feedback would
be very welcome!).

This is wrong. You should enable ACPI, and only disable ACPI_PROCESSOR.
Disabling ACPI is known to cause bugs with Linux on some machines.
