solved (at least, it's been working fine for a couple hours) by adding "i8042.dumbkbd=1 i8042.nomux=1" to the kernel command line in /etc/default/grub ( GRUB_CMDLINE_LINUX = "i8042.dumbkbd=1 i8042.nomux=1" ). don't know what they do... I had those since a couple years, but removed it after some upgrade. Adding xev output to see if it helps.
