Greetings! I found a message in my dmesg that said to notify this address if I find the kernel option acpi_apic_instance=2 to work better than the default setting. On this Clevo M541N laptop, the difference is apparent because without that option, I can only suspend once. On the second attempt it will make some noises with the optical drive, but it doesn't turn the display off after fading to black, or park the HDD's head. The kernel is then unresponsive to Magic SysRq keys as well and only the power switch helps. With the option set to "2" I found that I can suspend and resume as many times as I want. This is on Ubuntu 10.04 beta1, kernel version 2.6.32.16.17 on i386. I can provide more information to you if you need. -- Bálint Magyar -- 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
