Hello!

Summary of bugs:

1) ifdown eth[0-2] && rmmod 8139too ends in:
kernel: unregister_netdevice: waiting for eth0 to become free. Usage
count=1
(endless loop, machine unusable)

2) echo -n disk > /sys/power/state
bad: scheduling while atomic!
kernel: [<d10a624f>] rtl8139_suspend+0x6f/0xa0 [8139too]
kernel: [pci_device_suspend+40/48] pci_device_suspend+0x28/0x30

The success story is: the kernel compiles, boots and does it's job. This
motherboard got tree rtl- network chips on board, two of them configured
and running. Now I'm playing with the suspend to disk features ...

First try as in 2) gives exactly tree Oops (full output below) while
trying
suspending the ether devices.
So rebooted, and tried over with unloading the 8139too module first.
pmdisk
worked(!) that way in test-3. But first look at this:
