May be Len could try to debug this issue, as he is the only one with

One thought is that EC GPE is not present in GPE scope, thus it will
be not configured by the
time 6217' code is executed. So, in theory, 6217 could try to disable
EC GPE.
In acpi_install_gpe_handler, Linux always disables the GPE before
installing a GPE handler.
After 6217 is applied, when installing EC GPE handler, Linux will invoke
acpi_hw_write_gpe_enable_reg to try to disable EC GPE which is not done
before. Don't know if this is related.
No, EC GPE handler is installed later. Thus the error is triggered
during execution of 6217 code...
