SLES 11 SP1 : Unable to load ib_ipoib module

SUSE Linux Enterprise Server SLES Networking
1

Hello everyone,

I’m trying to load ib_ipoib module on a SLES 11 SP1 server to configure IP over Infiniband but it didn’t work :

raad-bak2:~ # modprobe ib_ipoib FATAL: Error inserting ib_ipoib (/lib/modules/2.6.32.12-0.7-default/updates/drivers/infiniband/ulp/ipoib/ib_ipoib.ko): Unknown symbol in module, or unknown parameter (see dmesg)

That ib_ipoib.ko file is from the Mellanox software stack that I installed :

raad-bak2:~ # rpm -qf /lib/modules/2.6.32.12-0.7-default/updates/drivers/infiniband/ulp/ipoib/ib_ipoib.ko mlnx-ofa_kernel-kmp-default-1.5.3_2.6.32.12_0.7-OFED.1.5.3.3.1.0.sles11sp1

When I look into dmesg :

Feb 12 17:37:10 raad-bak2 kernel: [603002.870941] ib_ipoib: Unknown symbol icmpv6_send

All the others ib modules are loaded :

[CODE]raad-bak2:~ # service openibd status

HCA driver loaded

The following OFED modules are loaded:

mlx4_core
mlx4_ib
mlx4_en
ib_mthca
ib_uverbs
ib_umad
ib_sa
ib_cm
ib_mad
ib_core
iw_cxgb3
iw_nes[/CODE]

And I can see the IB card :

raad-bak2:~ # lspci | grep Mella 82:00.0 Network controller: Mellanox Technologies Device 1003

I tried to disable ipv6 and to find some ipv6 packages to install but I didn’t find anything useful, I’m always stuck with the previous Unknown symbol messages.

Do you have any idea of what I can do to solve this issue ?

Thanks

Jeremy,

I tried to disable ipv6 and to find some ipv6 packages to install but I didn’t find anything useful, I’m always stuck with the previous Unknown symbol messages.

seems like that module explicitly requires ipv6 support in the kernel, so you need to activate IPv6 (or rather: make sure the proper kernel modules are loaded).

The symbol itself is defined in the kernel module “ipv6”, so you might try to start with a preceding “modprobe ipv6”.

Jens
