next in thread | raw e-mail | index | archive | help
After rebuilding world and installing, I rebuilt the drm-515
port and the accompanying gpu-firmware. This port has worked
upto this update. Upon running xinit to load Xorg, I am
greeted with the panic following my .sig (text extracted from
/var/crash/core.txt.1).
As a side note, 'pkg delete -f drm-515' followed by
building and install /usr/ports/graphics/drm-mod
selects the drm-66-kmod port. The ends up in a endless
loop of reboots when loading the radeonkms.ko module.
