[Xen-devel] Xen 3.4 fails to shutdown on a Dell E6400 machine

[Tom Rotenberg <tom.rotenberg@xxxxxxxxx>]

Hi,

I am using a Dell E6400 machine with Xen 3.4 version, and the Xen hypervisor fails to shutdown the machine.

Here are my test results:
1. When booting with a regular Linux (without Xen), then running the command: 'shutdown -hP now' causes the machine to be shut-down.
2. When using Xen 3.4, and running the command: 'shutdown -hP now', the machine looks like it was shutdown, but it's still on. It looks, like the Xen's code, didn't shut it down "completely".
The last log lines of Xen are:
[   60.511271] sd 0:0:0:0: [sda] Synchronizing SCSI cache

It looks like the hypervisor said he was enetring "ACPI S5 state", but didn't do it.

Can someone please help me with this issue?

Tom
