Hello, I have updated the kernel and now see a different issue with paths. Instead of gaining an extra path, I lose all paths but the one I issue the lip reset on.

Specifically added when running the command below: echo 1 > /sys/class/fc_host/host15/issue_lip There should be four paths total but if I run the command above five times, I will see nine total paths. The server will hang and require a reboot eventually as multiple hung_task_timeout errors show up in logs.

The number of paths grow after each bus reset causing instability with the OS. I have attached logs.zip which contains four files.
