apparently one driver (tpm_tis) was blocking the startup. i tried editing /etc/default/grub but this did not work, dmesg did the same output. but then i disabled the module tpm_tis alltogether by adding to /etc/modprobe.d/blacklist.conf this pushed startup down to 17s after bios - 31 seconds from cold start | |||
