Hi Po-Hsu Lin, I think AHCI has no native support for EEH; the last news I found is an attempt to include such support from 2015, but got denied upstream [0]. When a driver has no native support, EEH works by using what is called the hotplug approach, which is to PCI-remove the device. When it comes to storage devices with filesystem mounted and in-flight I/O, this is very dangerous and prone to failure.
So, I'm not sure how this test works, but one alternative would be skip testing with AHCI, or at least test it with no/idle filesystem mounted.
