Here is the major change between the boot logs: ACPI : EC: EC stopped ACPI Exception: AE_BAD_PARAMETER, Returned by Handler for [EmbeddedControl] (20160422/evregion-300) ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0._REG] (Node f5d09870), AE_BAD_PARAMETER (20160422/psparse-542) ACPI Exception: AE_BAD_PARAMETER, from region _REG, [EmbeddedControl] (20160422/evregion-397) ACPI Exception: AE_BAD_PARAMETER, Returned by Handler for [EmbeddedControl] (20160422/evregion-300) ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0._REG] (Node f5d09870), AE_BAD_PARAMETER (20160422/psparse-542) ACPI Exception: AE_BAD_PARAMETER, from region _REG, [EmbeddedControl] (20160422/evregion-397) ACPI : EC: GPE = 0x19, I/O: command/status = 0x66, data = 0x62 ACPI : EC: EC started The only config changes between the kernels were enabling MMC block devices and DM_CRYPT. Not likely to cause the above, I'd think. Does that ring a bell for someone? This little machine has only an SSD without TRIM, so bisecting is not really an option. I can provide more info and test patches, though.
