Zhao Yakui 20edd74fcf ACPI: Ignore AE_NOT_FOUND error of EC _REG method and continue to initialize EC ... On some broken BIOS the ACPI object in EC _REG method can't be found in ACPI namespace, which causes that the status code of AE_NOT_FOUND is returned by the EC _REG object. In such case the EC device can't be initialized correctly, which causes that battery/AC adapter can't work normally. As the EC address space handler is not removed and the memory pointed by its input argument is already free, sometimes the kernel will also be panic when EC internal register is still accessed. But the windows can work well on such broken BIOS. Maybe it will be reasonable that OS ignores the AE_NOT_FOUND error returned by the EC _REG object and continues to initialize EC device on some broken BIOS. For example: the ACPI object in EC _REG method can't be found and status error code is AE_NOT_FOUND. http://bugzilla.kernel.org/show_bug.cgi?id=8953 http://bugzilla.kernel.org/show_bug.cgi?id=10237 lenb: we may find a more general solution to this in the future.
