After a recent update on my dual boot hp laptop with secure boot disabled, whenever I switch back to linux (from windows 10) on the default kernel (4.4.0-145) the boot process gets stuck in this loop with the basic error message:
Unexpected IRQ trap at vector 07

Switching to the previous kernel lets me boot fine and then the default kernel works again on the next boot.
More specifically, it happened after I played a game on windows and rebooted right after, though I might be wrong about this.
Also, I don't know if this is related but sometimes when I reboot my linux os, when the computer starts up to elementary again immediately, without using windows in between boots, the screen shows exactly as it was right before it shut down with the applications open as they were etc, and then it switches right away to a "fresh" screen, the one you see after booting but not logged in.
