Yes, you was right. I fixed it! :)
However now I have another (strange) problem.
Attached you can find my patch to add power managament to the new
version of file "drivers/net/au1000_eth.c" that implements the
PHY-layer support.
Please, note the hack after the function mii_probe() called by
au1000_lowlevel_probe().
Kernel messages during suspend are:
hostname:~# apm --suspend
Stopping tasks: ===============================|
au1xxx_pm_prepare: state = 3
usbdev1.1_ep81: PM: suspend 0->2, parent 1-0:1.0 already 1

au1xxx_pm_enter: state = 3

au_sleep: Zzz...
au_sleep: Yep!

The first strange thing is that this time the kernel messages stop
after "au1xxx_pm_prepare: state = 3" and not after "au_sleep: Zzz..."
as before the merge! Maybe something as changed in serial console
magement?
The second strange thing is that _only_ calling the mii_probe()
the resume works correctly, otherwise the CPU loops forever
calling the au1000_lowlevel_probe() without showing the printk()
messages through the serial console. =:-o
Suggestions?
Ciao,
Rodolfo
