Hi Chris,

i just reverted this pull of your merge window patches in my 3.0.0-rc2 tree:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8c1c77ff9be27137fa7cbbf51efedef1a2ae915b;hp=f3ae1c75203535f65448517e46c8dd70a56b6c71

And you were right: The problem still exists. So it might be from the PCI subsystem :-(

Well then, i'll reset my tree and look for differences in the PCI boot messages.

Thanks,
Oliver
