Hi,
I upgraded my ThinkPad 560 to 4.1 today and the network is not working
well. NFS seems to hang as soon as I try to transfer a big file. It
happens 4.1 as well as the latest (as of two days ago) 4-stable.
Normal network stuff seems fine, at least I can transfer stuff like
the kernel with ftp.
I'm not sure if it's related but I'm using a Linksys EtherFast 10/100.
It used to work fine with the following patch to 3-stable. Looking at
sys/dev/ed, it seems some of the stuff were merged but not all of it.
I tried to apply the patch by hand but not being a kernel buff at all,
I can't get anything to work. ;)
Does anyone have any idea what I should do?
Satoshi
