OK I checked out the kernel with the SHA number above and applied the patch series
and rebuilt and reinstalled the kernel. I checked out v36.0 of rdma-core and rebuilt
that. rdma is version 5.9.0 but I doubt that will have any effect. My startup script
is

export LD_LIBRARY_PATH=/home/bob/src/rdma-core/build/lib/:/usr/local/lib:/usr/lib

sudo ip link set dev enp0s3 mtu 8500

sudo ip addr add dev enp0s3 fe80::0a00:27ff:fe94:8a69/64

sudo rdma link add rxe0 type rxe netdev enp0s3

I am running on a Virtualbox VM instance of Ubuntu 21.04 with 20 cores and 8GB of RAM.

The test looks like

sudo ./check -q srp/001

srp/001 (Create and remove LUNs) [passed]

runtime 1.174s ... 1.236s

There were no issues.

Any guesses what else to look at?

Thanks,

Bob
