(In reply to Graham Perrin from comment #3) Given the panic with drm-current-kmod built, packaged and installed from source, I decided to (temporarily) downgrade to drm-current-kmod-5.4.144.g20211012 built from 61b661339366b6ee95ca1de0667979da9240c6b8 (2021-10-25). ---- Maybe worth mentioning, at the times of the panics I had: % sysrc -f /etc/rc.conf kld_list kld_list: fusefs radeonkms if_iwlwifi % – loaded, however I was not actually using the driver (no compatible hardware at the moment). No longer. I'm back to just fusefs radeonkms ---- Also, I nearly always build my CURRENT with GENERIC-NODEBUG.
