Hi Michel,

yes it only happens on shutdown with a EDID blob passed at boot. Actually the
EDID blob passed I don't think is invalid, I don't know where it is getting the
one in the trace from that could be from perhaps the monitor itself.

Is the kernel there trying to open the EDID blob on a umounted fs?
