That breaks too - hangs similarly during suspend. I enabled RTC tracing 
and every time it prints out different hash matches after reboot - 
tty/tty21, pcie04  and latest is 

[    0.865296] pcieport 0000:00:1c.1: hash matches

Also when the suspend fails the immediate boot after that I get a USB 
error on startup - unable to enumerate usb device on port 1. This error is 
not present on normal boots.
