| |
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.
