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

Maybe we can figure out what's common between our systems since I
imagine if everyone were getting this error then this bug would be
getting more attention.

I'll also note this started for me with 5.15. 5.13 and earlier did not
exhibit this error. System seems to run fine though. No noticeable
degradation in performance or functionality.

Output of my inxi:
