With 5-stable as of last night (5.4-PRERELEASE #0: Thu Mar 3 21:41:55 JST 2005), on an IBM ThinkPad X20, running 'zzz' produces the following messages on the console: ACPI-0501: *** Error: Handler for [EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE ACPI-1304: *** Error: Method execution failed [\\_SB_.PCI0.ISA_.EC__.SYSL] (Node 0xc16d8040), AE_NO_HARDWARE_RESPONSE ACPI-1304: *** Error: Method execution failed [\\_SI_._SST] (Node 0xc16dd480), AE_NO_HARDWARE_RESPONSE ACPI-0306: *** Error: Method _SST failed, AE_NO_HARDWARE_RESPONSE The system then appears to sleep (however, characters are still visible on the display under bright light (though the backlight is off) and the "sleeping" moon indicator light does not light as it did with 4-stable). The system wakes up and continues operating with no trouble, so perhaps this is no cause for concern, but if anyone can explain the messages, I'd appreciate it. dmesg is attached. -- Tod McQuillin -------------- next part -------------- Waiting (max 60 seconds) for system process `vnlru' to stop...done Waiting (max 60 seconds) for system process `bufdaemon' to stop...done Waiting (max 60 seconds) for system process `syncer' to stop...
