Alexandre, can you try patch "[PATCH v2] Avoid that ATA error handling can trigger a kernel hang or oops" (https://www.mail-archive.com/linux-scsi@vger.kernel.org/msg71189.html)?

Thanks. I confirm that applying it on top of 4.15.4 seems to make the problem go away on all affected machines. I write 'seems' just because I can't quite prove the oops won't happen any more, but I'm pretty sure if it were to, it would have already ;-) Thanks, again!
