AGAIN: Do *NOT* build kernel modules in poudriere unless you can guarantee it's using the *EXACT SAME* kernel configuration and sources, you must solve this discrepancy: > > If you are asking if /usr/src is the same when building ports and > kernel then again, no, because when building ports the jail's /usr/src > is used, whereas when building the kernel the host's /usr/src is used. > > But I verified that both are the same, i.e., > > diff -r /usr/src /usr/local/poudriere/jails/12rel1/usr/src > > doesn't return any differences, apart from the additional kernel > configuration. They are both 12.1-RELEASE-p3 (checked the version > against sources in Github and SVN). ...and "additional kernel configuration" is the thing that MIGHT break the module in build if the kernel config has any impact on sources that the module uses. I still haven't understood why you cannot boot without amdgpu, and then built (a) kernel, (b) firmware, (c) amdgpu and DRM drivers all directly from /usr/src and updated /usr/ports *ON THE MACHINE WITH THE AMD VGA CARD*. There are way too many variables in the mix.
