Massive Lockup

[Olaf Flebbe]

Hi,

I have problems with the eepro100.c network driver. 
(Otherwise I should not waste bandwith ...) 

The network adapter is built into an asus m8000 series laptop

lspci detects:

Looks like it is driven by the cardbus bridge. (But is not on a PCMCIA
card, it is built in!)

Using it with a kernel module.

When I use the laptop with massive NFS traffic the driver supplied by
kernel 2.2.10 locks the laptop complete after a ~30 Min. 

I see several kernel messages:

I downloaded 1.09l from the web page and tried it on the 2.2.10 kernel:
One sees several messages (see below) and random network timeouts of
~3sec duration...

1.09l seems to be more stable, but it seem to crash the machine after
~2hours. This is better, but still worse. It has a good point, though:
After waking the laptop up from suspend to RAM, the network still works,
opposed to the vanilla 2.2.10 eepro100.c driver.

Most of the time the network adapters is reset and it works again but
sometimes the computer  locks up completly. The messages `Trying to
restart the transmitter' are comming at a rate of about 6 per minute for
heavy traffic!

Is it worth to put on debugging? debug=5 on the command line? Is it
worth posting more kernel messages?? (BTW: the network is 10MBit)
