I don't have a better idea about this, it looks like it's a h/w issue to me.
The GPE17 is triggerred by EC, so I can't figure out a proper fix for this
issue.
The feasible workaround would be ignore it by adding below line to the kernel
cmdline
acpi_mask_gpe=0x17
There is no updated BIOS to address this issue, so I believe there should be a
way to negotiate with the BIOS to stop the GPE17 flooding.
If you want to better fix the issue, could you contact HP's customer support to
see if they can shed some light on this?
Thanks.
