Ok, I just had time to reproduce this without tainting. It was with 3.2.5
though since I'm debugging a battery power use issue too.
I confirmed that the problem only happens when I do NFS copies. Doing the
same copy with rsync over SSH works fine.
I'm not much of a kernel guy, but it looks like there is a memory problem,
which in turn causes the network driver to deadlock waiting on RAM with
interrupts turned off (mouse cursor won't move). Eventually it gets a bit of
the special RAM it seems to need, at that point, my frozen mouse pointer
unfreezes until it locks again soon after.
So there are 2 problems
1) memory issue
2) driver waits for RAM with interrupts turned off
The log below shows offlineimap first getting memory allocation problems
as soon after I start the copy, then firefox, and some:
ieee80211 phy0: failed to reallocate TX buffer
No taint flags this time.
I'll paste a few lines below.
Any idea what's going on, what bucket of RAM is an issue for the driver
(total RAM is more than plenty), and where I should go from there?

Thanks,
Marc
