The screen flashes once very quickly and the whole machine hangs, and it leaves no information in either /sys/class/drm/card0/error or /sys/fs/pstore (the laptop doesn't have ECC and I'm trying to use EFI variables for this). There are a few occasions where instead of hanging the kernel outputs the errors in the files I'll attach (2 dmesgs from 2 runs where this happened) while allowing me to finish typing my password and booting.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
