We have encountered the following problems several times:
    1、A raid slot or hardware problem causes block device loss.
    2、Continue to issue IO requests to the problematic block device.
    3、The system possibly crash after a few hours.

What kernel is this on?

I have a customer that recently hit this issue on 4.12.14-122.74
SLE12-SP5 kernel.

I think need to engage SuSE support and engineering, then, as this
is not a kernel supported by upstream devs. I'd be saying the same
thing if this was an RHEL frankenkernel, too.

roger that, should not be a problem, thank you!
