[Bug 1970074] Re: UBSAN: array-index-out-of-bounds in /build/linux-9H675w/linux-5.15.0/drivers/ata/libahci.c:968:41

From analysis of our setup at work, it should be the JMicron SATA Controller.
It works with kernel 5.8 (Ubuntu 20.04) and fails with kernel 5.15 (Ubuntu 22.04).
No other kernel versions tested yet.

We already contacted our manufacturer (Icy Dock), but no feedback yet.
