Solutions you've tried
Use Qubes VM kernel. Works.

Looks like a regression of #2844 . But note the "solution" there was disabling gcc plugins for out-of-tree module builds, which may or may not be desirable in your case.

Use Qubes VM kernel. Works.

This is generally better solution, in line of #5212

Looks like a regression of #2844 .

I'm interpreting this to mean that this issue should be closed as a duplicate of #2844, and #2844 should be re-opened due to the regression. (If this is incorrect, please let me know and/or feel free to undo these actions.)

Duplicate of #2844

The issue was the fix was only in a master branch (kernel-latest-* packages), but not relevant stable branches. Fixed (4.19.82, 4.14.152).
