Hi,
when upgrading from v4.7-rc2 to rc6 on my Dell Mini 9, battery and
temperature status info got bogus. 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.
Thanks,
Wolfram
