Hi,

Im using ACPI on my Acer Travelmate 800 for a very long time.
I never had any big problems with it, until now.

Today I activated my builtin ethernet card (BCM4401) because I wanted to
copy a large amount of data. (normally I only use WLAN).

First I copied some files from my notebook to another computer.
Everything worked fine.

But then I tried to copy an CD-Image file from our fileserver to my
notebook. As soon as the transfer started, the following error messages
appeared
in my syslog and the transfer stalled. 

	b44: eth0: Link is down.
	b44: eth0: Link is up at 100 Mbps, full duplex.
	b44: eth0: Flow control is on for TX and on for RX.
	<repeating>
	.........

Looking at the switch I saw that the card was indeed resetting itself.

-------------
	Server		-> 	Notebook 	OK
	Notebook	->	Server		NOT OK
-------------

Since I was running 2.6.0 I switched back to 2.4.23 to see if it had the
same problem.

To sum it up:

	2.6.0	   +	b44/bcm4400(Broadcom module) + pci=noacpi 	NOT OK
	2.4.2[23]  +	b44/bcm4400(Broadcom module) + pci=noacpi	NOT OK

BUT
	2.6.0      +	b44 + acpi=off OK

With acpi completely off the transfer worked in both directions without
any problems.


Does anybody here have a clue why?
I don't understand how ACPI can interfer with the card, since trying
pci=noacpi didn't work either.
		

Thanks in advance,
Michael
