I'll try it, although I don't think I'll get any data on the problem. The unmodified DSDT (bios 1.11) lacks an S3 sleep object, so I had to modify the DSDT even to get S3 to sleep at all. See <http://bugzilla.kernel.org/show_bug.cgi?id=3534> for that discussion. In additional comment #4 there (2004-10-14), you said: The root cause of [the missing S3 object] failure is that linux is using element in const char *acpi_gbl_sleep_state_names[ACPI_S_STATE_COUNT] = { "\_S0_", "\_S1_", "\_S2_", "\_S3_", "\_S4_", "\_S5_" }; to call acpi_get_sleep_type_data, but your box define _S3 under the device PNP0A03. So, the evaluating \_S3 will fail. The workaround in DSDT is to change _S3 to \_S3_ . We can fix it in acpi driver soon. It looks unchanged in a recent acpi driver (drivers/acpi/utilities/utglobal.c, line 170, 2.6.16-rc2), so I suspect S3 won't happen with the vanilla DSDT. (Sorry, I was away for 10 days and also just saw your info requests in the bugme #5989.) -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1. ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
