client hangs at reboot network card shutdown

[Barry Cisna]

Hello All,

We have about 100 dell optiplex sx280 that runs under the tg3 driver as
a TC.

With ltsp-server 5.4.5-x when either shutting down or rebooting these
TC's from login dialogue box,when 'shutting down eth0" on rebooting
dialogue they will go no further to actually reboot.

It seems I read some time back this to be a known problem,but I can not
remember what the workaround was,and can not find this now.

Thank You,
Barry

Try disabling the 'network' service inside the chroot. The network
settings are retrieved by the initram so i cant see why they would need
to be shutdown by the operating system, I have not tested this so I'm
unsure if this would cause other issues. Send feedback of the results of
your findings.

Joshua,

I disabled the network service from starting in the client / chroot.
Rebooted server,,,rebooted client.

After this config change the TC just shows the Centos splash screen and
shows the "rebooting" in upper left of monitor,,,and no more activity on
the ethernet wire.
In other words the TC does not get as far as previously in the
shutdown/reboot procedure.
I tried this on three different TC's from Intel,,and Broadcom nic
varieties,,,for completeness.
Switched back to chkconfig network on,,in chroot,,and reboot goes all
the way to 'shutting down eth0",,,and stops.

Usually this stems from issues with power management, I don't think the networking is the problem. You might check the power management APM/ACPI in the client's bios.
You might need to have reboot=pci or noapci parameters passed to the client when it boots the kernel.
