Running many fio jobs on 10 NVMF/RDMA ram disks, and bringing down and back up the interfaces in a loop uncovers this crash. I'm not sure if this has been reported/fixed? I'm using the for-linus branch of linux-block + sagi's 5 patches on the host. What this test tickles is keep-alive recovery in the presence of heavy raw/direct IO. Before the crash there are logs of these logged, which is probably expected:
With what fixes does this happen? This looks pretty similar to an issue you reported before.
