However, with 2.6.16-rc1 with the acpi-20060113 patch, the first sleep and wake goes fine and the second sleep hangs at the 'Stopping tasks'. With tons of debugging turned on, the second sleep does not hang, but the wakeup hangs. With 0x1F as the acpi debug_level, the second sleep still hangs and produces some output across a serial console. In the second sleep (after the second 'Stopping tasks'), it endlessly repeats a short sequence of exregion-0182 ... exregion-0287 ... exregion-0182 ... The machine is a TP 600X with the latest (1.11) BIOS and a fixed DSDT so that it can S3 sleep at all. -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
