Looks like some potential memory corruption? 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.
