The machine I'm using is a Dell Optiplex 745, running Scientific
Linux 5 with a default fairly old kernel (2.6.18-53.1.4.el5).
/proc/acpi/wakeup contains this:
Device Sleep state Status
VBTN 4 * enabled
PCI0 5 disabled
PCI4 5 disabled
PCI2 5 disabled
PCI3 5 disabled
PCI1 5 disabled
PCI5 5 disabled
PCI6 5 disabled
USB0 3 disabled
USB1 3 disabled
USB2 3 disabled
USB3 3 disabled
USB4 3 disabled
There doesn't seem to be a NIC listed there...? So it's a bit
difficult to know what to try to enable as per your instructions.
Thanks a lot...
