I'll do that tomorrow, TIA for your interest in the issue. Today I spent several hours to bisect the S0ix "regression" on Asus E200HA, I put regression in quotes because S0ix only ever worked with gross hacks like poking registers using busybox devmem. Anyway, the gross hack worked on v4.12 and stopped working in v4.13-rc and the culprit is d31fd43c0f9a4 "clk: x86: Do not gate clocks enabled by the firmware" (I'll report this properly in a seperate mail). But I guess that's not the part you're interested in, the bug entry should cover interaction of dw i2c, acpi pm, acpi-lpss and ACPI OpRegion, right?
