Good idea Jani!

Removed bumblebee and the proprietary nvidia driver. This didn't fix things, but it did allow me to go further before things locked up. Including actual system logging!

Attached a dmesg output I got before things fell over. Upon booting, it seems the nouveau driver kms fails, then it falls over to i915. You can see nouveau initializing around 2.2 seconds in the log, then timing out at around 16 seconds. The first actual kernel crashes come later, starting with ieee80211 complaints. I was able to dmesg to a logfile and scp it away before things really unraveled. Hitting ctl-alt-del (all on console) induces a hard hang.

blacklisting nouveau and rebuilding the initfs, it's back to the original problem of not even booting happily. Disabling the discrete card in bios does not change this behavior. The tail of its problems again shows up eventually on my second monitor, looking similar to the initial attachments where drm_atomic_helper is timing out. Wait... as I type this it eventually got to single user mode, second dmesg dump retrieved before it hang (again on ctl-alt-del). But, dumping that to a text file didn't make it to disk, the crash didn't flush the disk write buffer :(
