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

2022-06-06 Thread Markus Maier
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.

2022-06-05 Thread Bob Lawrence
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.
