Topic: SME Server 6.5 don't power off automatically

[wpanessi]

Hello every body.
 I have install SME Server 6.5 in one IBM/PC. When I power off from server manager the system is stoped in the "Power off" legend and I need press the power off/Suspend button to power off definitively. The problem is : that server don't have monitor and I've not idea if it is just halt or not.

Any idea to solve this problem ?

many thank

(I'm sorry my english)

Is the server a P4 with hyperthreading?

If it is, the problem with 2.4.18+   kernels and ACPI/APM is probably biting you. It has something to do with them not being safe for an SMP kernel, because they're not sure if  both processors are ready to be stopped. Sometimes adding apm=power_off works, but it depends, you might try disabling both apm and acpi and see if that helps.

I've had some success with disabling apm and acpi in grub.conf, but I'd advise you to read up on it, and not just cut and copy from my reply
