drm kernel messages log

on a 16-CURRENT system with iGPU intel i5 650, drm-612-kmod results in failure of x11 with lkpi_vmf_insert_pfn_prot_locked: page rename failed: page iked: page rename failed: page is mapped,the only method that seems to work to get x11 show up instead of a blackscreen is setting AccelMethod to none
vt loads and shows up fine until startx
x11 on the same 16-CURRENT system work fine with drm-61-kmod and drm-66-kmod without needing to set Accelmethod to none

i have attached some drm logs i have collected using
compat.linuxkpi.i915_mmio_debug=1
compat.linuxkpi.drm_debug=0x1e
compat.linuxkpi.rcu_debug=1
compat.linuxkpi.debug=1

the issue seems similar to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=296195
