As a wild guess I tried "acpi_sleep=s4_nonvs", but it didn't help.
In fact it didn't seem to work. The kernel log says that NVS was still saved and restored.
$ dmesg | grep -i nvs [ 0.000000] BIOS-e820: 000000001f790000 - 000000001f7d0000 (ACPI NVS) [ 0.000000] Kernel command line: root=/dev/sda2 ro resume=/dev/sda2 resume_offset=144480 quiet acpi_sleep=s4_nonvs [ 91.105449] PM: Saving platform NVS memory [ 91.106707] PM: Restoring platform NVS memory
Thanks Alan
