Subject: Re: 3.2.8/amd64 full interrupt hangs and deadlocks under big network copies (page allocation failure)
As an update I upgraded the laptop from 4GB to 8GB and I still cannot to a big
copy via NFS without the laptop hanging pretty badly.
To be clear, I've had the problem both over wired ethernet (e1000e) and
intel 5300agn (iwlwifi)
Doing the same copy with rsync over ssh worked.
I also did a big NFS copy inbound instead of outbound and that seems to have
worke too.
Can someone tell me there is something I can do to work around the problem,
and get the underlying problem fixed.
(well, looks like not using NFS is the workaround)
Thanks,
Marc
I tried the copy over wifi this time instead of e1000e, and got:
