My NFS root test systems stopped booting with 2.6.37-rc1. It just hangs after entering user space. The NFS root setup uses a slightly fancy parameter setup to minimize network traffic: nfsroot=10.23.204.1:/home/nfsroot/edwin,nocto,acregmin=86400,acregmax=86400,acdirmin=86400,acdirmax=86400 root=/dev/nfs I bisected it down to this commit from Bryan. Unfortunately it's not trivially revertable because that conflicts with later patches. commit d1bacf9eb2fd0e7ef870acf84b9e3b157dcfa7dc Author: Bryan Schumaker <bjschuma@xxxxxxxxxx> Date: Fri Sep 24 14:48:42 2010 -0400 NFS: add readdir cache array -Andi -- ak@xxxxxxxxxxxxxxx -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
