Currently, the kernel emits a notice at boot, warning about the usage of
trace_printk(). Disabling samples in efaa3edaaa ("Do not build samples
for Debian/Ubuntu") apparently wasn't enough to get rid of that. So
disable more sample and testing stuff that might call this function.
The Debian LTS kernel does not have CONFIG_ACPI_I2C_OPREGION set. This
is likely due to its dependency on CONFIG_I2C=y. Thus explicitly set
those two options.
