Subject: rdma_rxe: Kernel bug during QP cleanup

Hello,

The below output appeared on the serial console while I was using the rdma_rxe
driver. I don't think this is caused by the change I made to this driver (the
patch I posted earlier on the linux-rdma mailing list). Can someone have a look
at this?

Thanks,

Bart.
