[g.schardt]

can you tell me, how to add this parameters to the kernel boot parameter ? or do you mount after booting ?

if you are using a bootloader see Documentation/nfsroot.txt in the linux
source tree (a quick example: nfsroot=192.168.0.1:/nfsroot,tcp,no_lock).

if you are using dhcp, then you have to tell your dhcp server to serv 
these paramters (for the isc dhcpd: option root-path "/nfsroot,tcp,no_lock").

Virtex TEMAC 1000Mb/s trouble, but 100b/s is working

[alex_snippet]

Hi all!

I'm porting Linux for custom board based on Virtex4 FX, vanilla kernel
2.6.22.5 , Xilinx EDK 9.1 BSP, 
ELDK41 - cross-compiler 
target nfs-root pointed to ELDK41/ppc_4xx

Kernel command line:
Linux/PPC load: root=/dev/nfs rw console=ttyS0,9600
nfsroot=192.168.0.1:/target
ip=on

All work successfully was done, i tested all at 100Mb's connection speed,
but yesterday my customer said that with 1Gbit connection it did't work :(
end of log following:

Load process was friezed at this point. When connection speed is 100Mb/s
everything is ok.

Please advise me what to do, i tried to increase ppc core frequency from 100
to 300 MHz - the same problem. 
When i'm using virtual machine instead of real hardware it's working on
1000Gb/s :) but isn't on real hardware.
I'm using Fedora 7 as a host.
May be there are some nfs-demon settings?

Re: Virtex TEMAC 1000Mb/s trouble, but 100b/s is working

[schardt]

I have the same problem with the FX12 Minimodul, runing 2.6.23 kernel...

running the nfs-kernel-server on the host, i could mount the
nfs-directory from the target with -o nolock,tcp
running the nfs-user-kernel failed

with both server i could not mount root-fs in the boot process

i gave up at this moment and take the root-fs to flash memory

regards
georg

We have it working for our ML403. But we are not using the builtin-support
from the kernel.
We are using an initrd/initramfs for mounting the NFS (as this is much
easier for debugging (you can get a shell)).

We had problems with ubuntu as a host. Debian (Kernel 2.6.18) works fine for
us.

we use

tcp,no_lock

here.
