QorIQ T2080 Board NFS signal 11 problem

Hi, Im having a lot of issues trying to mount an NFS on my embebbed system.

My CPU is a T2080, powerpc arquitecture. It has compiled a kernel from Yocto(QorIQ NXP SDK 1.8):

LSB_VERSION="core-4.1-noarch:core-4.1-powerpc64"

DISTRIB_ID=fsl-networking

DISTRIB_RELEASE=QorIQ-SDK-V1.8

DISTRIB_CODENAME=daisy

DISTRIB_DESCRIPTION="fsl-networking (QorIQ SDK) QorIQ-SDK-V1.8"

The kernel versión is: 3.12.37-rt51-607906-101

These are the steps followed to mount the nfs folder until the error appears.

Server:

-Create the server folder on /mnt

-Give permissions to this folder(777)

-Create the file exports on /etc

-Fill with the dessired configuration

/mnt/nfs_share_server 192.168.5.0/24(rw,sync,no_root_squash,no_subtree_check)

-Export the configuration:

Exportfs -avr

-This is the result of the previous command:

exporting 192.168.5.0/24:/mnt/nfs_share_server

Client:

-Create the client folder on /mnt

-Give permissions to this folder(777)

-Check for nfs server with:

showmount -e 192.168.5.22:

-This is the result of the previous command:

Export list for 192.168.5.22:

/nfs_share_server 192.168.5.0/24

-Here, i mount the nfs folders with this command:

mount -t nfs 192.168.5.22:/mnt/nfs_share_server /mnt/nfs_share_client -o vers=2 -vvvv

-The versión of NFS doesnt matter, it gaves me the same error on kernel, which is:

[ 484.461483] rpc.mountd[2023]: unhandled signal 11 at 0000000000000000 **bleep** 000000001000b0f8 lr 000000001000b0f4 code 30001

After this, the RPC service is broken for this sesion until i restart it.

Also, after the signal 11, the system gives me a connection refuse message all the time.

It also gives me a connection refuse when i tried a showmount comand over the server ip.

I notice that it gives me a signal 11 error when i include a netmask on the exports file.

But when theres only an ip, it gives me a connection refuse:

/mnt/nfs_share_server 192.168.5.0/24() -signal 11 error

/mnt/nfs_share_server 192.168.5.0/16() -signal 11 error

/mnt/nfs_share_server 192.168.5.0() -refused conection

/mnt/nfs_share_server 192.168.5.22() -refused conection

/mnt/nfs_share_server 10.229.11.xx() -signal11 error

Last one is when i give an ip of an non-exitent system.

Its really weird, if anyone could help would be nice.

Thank you all
