[Xenomai-help] Can a network freeze caused by Xenomai ?

[VEYSSIERE Nicolas]

Hello,

I would like to know if it is possible that a network freeze been caused by the use of Xenomai ?

Here is my problem : we have 4 HP DL 360 G6 server. All are installed with the last update of Redhat Entreprise Linux 5.6.

All 4 have 4 physical ethernet interface (2 from intel chipset, 2 from broadcom chipset).

They all have a virtual ethernet interface on eth0 (named eth0:1).

2 of them have Xenomai installed (v2.5.5.2 with linux kernel v2.6.35.7).


The problem is : on 1 with Xenomai installed, (the other one is not running for the moment), and we regularly have 'network freeze', we can't ping it, it can't reach other computers, and we have to restart the OS.


Any help is welcome.

Regards,

Do you have the same issue with the latest stable release (v2.5.6)? If
yes, please try and capture the kernel logs from the boot, up to the
bug, via serial console, or via netconsole (but seeing the bug you
describe, serial console is a better idea).

Great ! thank you both, I will update the kernel and Xenomai, and retreive kernel logs.

2.6.35 may lack ipipe fixes we have in the latest versions now. So
updating this and the Xenomai release should be the first step.

Dear Gilles,

The problem also is that the linux kernel servers (and all mirrors)
seem down so that the vanilla kernel is difficult to get. Do you know
where you could try the 2.6.38.8 vanilla kernel so that I could try
this version of Xenomai ?

Thanks,

This one does not seem to be down:
