I previously recompiled my kernel to implement a variant of Rafael's patch from last November and was able to use it to determine that only the actual S3 state enter/exit (i.e., the writes to the PM1*_CONTROL in acpi_enter_sleep_state()) mattered - or, as you said, all the tests worked. I'd like to try 2.6.26 soon, but FWIW I did attempt 2.6.24 with the same results. -Jeff -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
