2.6.23-rc1 sky2 boot crash in sky2_mac_intr

[Florian Lohoff <flo@rfc822.org>]

Hi,
i am seeing irregular crashes on boot in the sky2_mac_intr. This is an
Fujitsu Siemens Lifebook E8110 with a Core Duo. Currently i suspect some
strange BIOS issues as the issues i see with the sky2 aka parity errors
etc i also see sometimes with the integrated ipw3945 which complains
about firmware errors. It seems the BIOS randomly fails to initialize
all the hardware. To reproduce this crash and catch it on the serial
console it took me around 12 boots. The machine is stable once correctly
booted and i work most of the day on it.
