I filed a bug in bugzilla, but I wasn't sure what category to put it in, so I suspect I ended up picking one that doesn't get looked at much.
https://bugzilla.kernel.org/show_bug.cgi?id=195051
The issue is that on a specific Acer laptop with a dual-core A9, if I don't disable the IOMMU using iommu=off, it has immediate and rapidly fatal filesystem corruption by the time a user logs into the desktop. What led me to try that was at one point I noticed an error message about the iommu in the logs. However, I did not have a chance to save that due to the corruption obliterating the log files.
