Subject: Clevo M541N and acpi_apic_instance=2

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.
