SSD errors

[Robert Nestor <rnestor%mac.com@localhost>]

I’m running NetBSD 9.1 on an amd64k system.  When I run it on a spinning disk I don’t see any errors, but when I install it on an SSD is see a lot of timeout and write errors.  Initially I thought it was a failing SSD as the one I’d first used was quite old, so I bought a new Samsung 870.  Right out of the box I’m seeing the same errors with it as well.  Here’s a short example of the two types of errors I’m seeing:

Feb 26 09:50:59 amd64k /netbsd: [   3.3392559] wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133), WRITE DMA FUA, NCQ (32 tags)

Is this a known issue with NetBSD running on SSD?  Is there some parameter I need in a kernel build that’s not in GENERIC that addresses this?

Thanks,
