Yes, everything else is the same - I'm just changing the kernel I'm booting. Your comment about gdm got me looking at the it's logs. I've attached all the greeter logs that were in /var/log/gdm. In particular, the last two lines of the log.4 looks bad. Those logs are a mix of the 6.5 and 6.6 kernels but I'm not sure which is which. I'll capture dmesg output from both the 6.5 and 6.6 boots and see if I can find anything useful.
