kernel log (from netconsole)
My new Kaby Lake laptop (HP 15-ay105n with an Intel i7-7500U) seems to not like Linux at all.
At seemingly random times, the system crashes (screen freezes, no caps lock blink, does not respond to magic SysRq commands) or I experience a normal kernel panic with the blinky caps lock. It's a bit difficult to capture logs for the crash since sometimes I get nothing even without starting X11. With netconsole and a few attempts, I managed to capture what might be related to this issue.
This problem seems to be present from earlier versions of the Kernel, so I suspect it's either a Kaby Lake-specific bug, a bug that was "dormant" until something in my hardware (kaby lake, the motherboard...) helped waking it or bad firmware from HP that might require special handling to work properly.
Hardware issue: HP replaced my motherboard.
