Sharma,

This is a problem with using ipoib interfaces on SLES for which I have
a patch. It will appear as an update to SLES shortly. If you would like
me to send you the patch directly, let me know.

Thanks.
Pat

Hi:

When I am trying to remove ipoib module on SLES10 machine, it is not
getting removed. I am using "modprobe -r ib_ipoib" command. This command
is not giving me any error but if i do lsmod, i still see the module
running. I have also tried rmmod.

Please note that on RHEL4 up3 kernel, I am able to remove the module.

Attached below is the output. I have also attached output from
/var/log/messages file below. Is it a bug in OFED  or SLES ?

Thanks,
Karun
