 850

My boot issue happens right after the BIOS when the initrd should be
loaded and then no grub (v2.0) menu appears.

It seems I could fix it for me disabling  Host Notify + Interrupts with
options i2c_i801 disable_features=0x30 and then rebuilding initrd.
The touchpad is still working. Still testing more days if it will hang
again.

Is there anything further I can do to help? I can't tell when this hang
was introduced. When I received the HP Arch was running 4.9 lts kernel
and it already hung there.
