Subject: [regression] NFS readdir change break fully cached nfs root
Date: Tue, 2 Nov 2010 19:00:51 +0100 [thread overview]
Message-ID: <20101102180051.GA26089@basil.fritz.box> (raw)
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.
