But there is a setiathome GPU task which reliably gives me a hard lockup within about 30 minutes of running. I actually had to do *two* emergency re-installs over the past week. Perhaps part of this was my fault ( running btrfs with lzo compression on my root partition ... ). But absolutely part of this was the hard lockups. I've tested all kinds of other things ( eg rebuilding lots of stuff under Gentoo ) ... I don't have a general stability issue even under hours of high load. But after restarting boinc with that same setiathome task ... <bang>!

Not sure what you were afraid of.  I don't think anyone has looked at
setiathome on ROCm.  I'd suggest filing a bug
(https://bugs.freedesktop.org) and attaching your dmesg output and
xorg log (if using X).  If there is a GPU reset, note that you will
need to restart your desktop environment because currently neither
glamor or any compositors support GL robustness extensions to reset
their contexts after a GPU reset.
