Hello
On this machine I get a lot of ACPI errors during boot. It's a samsung NF310
Netbook with a Intel Atom N550 CPU. Linux has been a bit dodgy on this machine,
I get other errors as well and have experienced a few crashes bug I'm not sure
if it's related to these errors.
It happens whith the included kernel in ubuntu 10.10 (2.6.35) and the latest rc
(2.6.37-rc2). It happens with both 32 bit and 64 bit kernels.
