Hi Bjorn,

Sure, you can find it attached.

I am getting some more kernel error messages during boot (that I planned to 
report later), they may or may not be related, so I just log them here for the 
sake of completeness - please feel free to ignore them if you think they are 
unrelated:

[    0.470960] pci_root PNP0A03:00: address space collision: host bridge 
window [mem 0x000cc000-0x000cffff] conflicts with Video ROM [mem  
0x000c0000-0x000ce9ff]
[    0.471052] pci_root PNP0A03:00: address space collision: host bridge  
window [mem 0x000ec000-0x000effff] conflicts with reserved [mem  
0x000ef000-0x000fffff]
(at least one of them seems to be covered by 
https://bugzilla.kernel.org/show_bug.cgi?id=38522 so I will wait until 3.1 is 
out before reporting)

Sometimes I also get this message - unfortunately, I could not yet find a 
pattern for when this occurs and when not:
[    1.480097] pci 0000:00:04.0: ASPM: Could not configure common clock

Kind regards,
Ralf
