If I add acpi_apic_instance=2 acpi_osi=Linux as kernel boot options (as suggested by my dmesg) when it resumes I get back to a virtual term but I'm not able to log in. After entering my username it just hangs there. nick -- 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
