At resume we try to get connector info but panic due to a bad pointer, maybe in one of the lists. Can you gdb your drm_kms_helper module and do "list *drm_mode_getconnector+0x295" to see what line this is? Also, what chipset do you have? Maybe I can reproduce it here with your kernel config. -- Jesse Barnes, Intel Open Source Technology Center
