https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227191 --- Comment #19 from Andriy Gapon <avg@FreeBSD.org> --- I am curious if anyone who had this problem before still has it. Especially, I am curious if they had an error message like in comment#1 and if that message went way. In addition to the prior analysis I'd like to add the following summary. - before base r330957 we ignored any _STA evaluation failure (which was performed in ACPICA contrib code) for the purpose of acpi_DeviceIsPresent and acpi_BatteryIsPresent - ACPICA 20180313 stopped evaluating _STA altogether - so, we added evaluation of _STA to acpi_DeviceIsPresent and acpi_BatteryIsPresent - one important difference is that now we ignore a failure only if _STA does not exist (AE_NOT_FOUND) - any other kind of failure is treated as a failure - apparently, on some systems we can get AE_NOT_EXIST when evaluating _STA - that error is not an evil twin of AE_NOT_FOUND, despite a very similar name, but a distinct error related to a missing handler for embedded controller (EC) address space - it's possible that for some people the problem was fixed by some changes in ACPICA and/or acpi_ec that fixed the AE_NOT_EXIST failure Still, I would like to re-iterate my proposal that we restore full pre-r330957 behaviour by ignoring any _STA error. -- You are receiving this mail because: You are on the CC list for the bug.
