You need to upgrade your kernel. It had a bug with eql targets in the
async logout path. It is fixed in 5.4 and 5.5 kernels.
Actually it was fixed in 5.3 too.
The weird thing here is that we get this error *before* we get the async
logout request.
Do you have multiple sessions? Is sdt accessed through session 22 (run
iscsiadm -m session -P 3 to see) or a different session? If a different
session is there more log and can you send it?
