NFS flakiness since _at_ last Friday

I'm seeing some real instability in NFS since approximately last Friday.
Intermittently, I'm seeing messages such as the following:

On the client machine:

Dec 20 23:18:22 dolphin kernel: impossible packet length (1820291) from
nfs server gateway:/mm
Dec 21 00:51:47 dolphin kernel: impossible packet length (1746474142)
from nfs server gateway:/mm

and

Dec 21 01:14:41 dolphin kernel: nfs send error 35 for server gateway:/mm
Dec 21 01:16:33 dolphin kernel: nfs send error 35 for server gateway:/mm
Dec 21 01:16:38 dolphin kernel: nfs send error 35 for server gateway:/mm
Dec 21 01:16:40 dolphin kernel: nfs server gateway:/mm: not responding
Dec 21 01:16:43 dolphin kernel: nfs server gateway:/mm: is alive again

On the server machine:

Dec 20 21:52:48 gateway kernel: nfsd send error 32
Dec 20 21:57:50 gateway kernel: nfsd send error 32
Dec 20 22:00:45 gateway kernel: nfsd send error 32
Dec 20 22:23:29 gateway kernel: nfsd send error 32
Dec 20 23:18:23 gateway kernel: nfsd send error 32

Then, ultimately, all NFS communication just breaks down
altogether until a reboot.

I'm also seeing "sillyrenames" left behind occasionally in nfs-mounted
directories.

There were a couple of nfs-related commits last Thursday, which I
believe are most likely the culprit, although I don't know which ones
exactly.
