Hi George,

Is the bios from the Soekris net6501 ACPI conform? (If not shame on me)

Did you first install on another machine (Hardware) the OS and put this 
medium (HDD/SSD) in the Soekris box?

<http://www.vdr-wiki.de/wiki/index.php/ACPI_Wakeup> is written in German but
declares the HEPT problematic 
on some hardware at the example with Debian Linux very fine and shows some main
boards with and without support. 

Or have a quick look at <https://bugzilla.kernel.org/show_bug.cgi?id=12013>

Did this main board have special options for enable and disable the HPET
in the bios and at the Soekris hardware this options should now be changed?

Wim Vandeputte was using the Debian 6.0 kernel version - 2.6.32-5-686 for a

At some main boards HPET must be disabled by setting the kernel parameter
it is not enough to discard this option during the kernel configuration, because
the RTC driver 
does emulating a HPET device.

I hope this was helping you out.

Kind regards
