Subject: 2.6.31-rc3 nfsv4 client regression (oops)


The NFSv4 client just oops'd on me...

NFSv4 client: 2.6.31-rc3, Fedora 10, x86-64
		    2.6.30 works, I think 2.6.31-rc1 worked too

NFSv4 server: 2.6.29.4-167.fc11.x86_64 (Fedora 11 kernel), F11, x86-64

Oops output captured at kerneloops.org: 
http://www.kerneloops.org/raw.php?rawid=537858&msgid=

Kernel config for 2.6.31-rc3, the problematic kernel, attached.
