2048 is TAINT_FIRMWARE_WORKAROUND. That seems to be set when linux thinks there is something wrong with ACPI tables:

arch/x86/pci/fixup.c: add_taint(TAINT_FIRMWARE_WORKAROUND, LOCKDEP_STILL_OK);
drivers/acpi/arm64/iort.c: if (WARN_TAINT(iort_node >= iort_end, TAINT_FIRMWARE_WORKAROUND,
drivers/dma/ioat/dca.c: add_taint(TAINT_FIRMWARE_WORKAROUND, LOCKDEP_STILL_OK);
drivers/firmware/efi/runtime-wrappers.c: add_taint(TAINT_FIRMWARE_WORKAROUND, LOCKDEP_NOW_UNRELIABLE);
drivers/iommu/intel/dmar.c: add_taint(TAINT_FIRMWARE_WORKAROUND, LOCKDEP_STILL_OK);

That would make sense to be happening on some systems where the tests were not running before.
