Subject: Re: [Intel-gfx] [PATCH v5 19/22] drm: restore
CONFIG_DRM_USE_DYNAMIC_DEBUG un-BROKEN
hi, Jim Cromie,
we send this report to you to consult that if there is any limitation to use
this CONFIG_DRM_USE_DYNAMIC_DEBUG?
attached config is a randconfig which has CONFIG_DRM_USE_DYNAMIC_DEBUG, the
kernel built with it failed to boot in our tests, but we also tested with some
other config then the issue cannot reproduce.
below full report FYI.
