Subject: 2.6.19.2 sky2/acpi crashes

Hi,

I'm running a macbook with a Marvell ethernet controller, and I have a
lots of freezes when using the ethernet controller under a load of
~100K/s. Since I'm running a 2.6.19.2 kernel, I'm able to get some
report from the kernel. Here they are :

As most of the time, the keyboard gets locked and the network driver is
down, I can get more informations.

Here my hardware configuration :
