driver 8139too prevents swsusp.

["Éric Brunet" <ebrunet-l5PIGlIYzrxGWvitb5QawA@public.gmane.org>]

Hello,

I have been trying S4 sleep on a 2.5.59 + acpi0123 patch kernel on my
computer (Shuttle motherboard, i845 chipset). The motherboard has an
integrated Realtek  ``RTL-8139/8139C/8139C+ (rev 10)'' ethernet card,
so I am using the 8139too driver compiled in the kernel.

When I try to ``echo 4 > /proc/acpi/sleep'', I have messages like:

=kdeinit entered refrigerator
=kalarmd entered refrigerator
=zsh entered refrigerator
=su entered refrigerator
=
[ wait a couple of seconds ]
 stopping tasks failed (1 tasks remaining)
Suspend failed: Not all processes stopped!
Restarting tasks...<6> Strange, eth0 not stopped
 done
init left refrigerator
pdflush left refrigerator
kswapd0 left refrigerator
kseriod left refrigerator

Indeed, I have a kernel thread called [eth0] in the ps output. I cannot
kill this process, but if I do ``ifconfig eth0 down'', the process
diseapear and the swsusp works better (see below). So it seems that
swsusp cannot put this [eth0] process in the refrigerator.

By the way, when I did my swsusp tests yesterday, I switched to runlevel 1
to experiment. After shutting down eth0 with ifconfig, sleep level 4
worked great: the computer went down and resumed flawlessly. However, I
tried again today before writing this bug report and I stayed in
runlevel 5 (I just switched to VT1 to see kernel messages). And today
I couldn't suspend either, I hit the BUG_ON in driver/ide/ide-disk.c:1557
I didn't bother to hand write down the oops, as the machine was frozen
and as I reflected that the stack trace was probably perfectly known.
If this oops is of some importance, I can try to reproduce and write
it.

Thanks for all your work,

	Éric Brunet
