Kernel messages during startup



Hi list,

every time I boot my laptop (HP Compaq 615) into Debian testing, some kernel 
messages are printed on the boot console:
[    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]
[    4.993532] shpchp 0000:00:01.0: Cannot reserve MMIO region
[    5.525413] SP5100 TCO timer: mmio address 0xfec000f0 already in use

(before upgrading to Linux 3.0, only the 2nd and 3rd of these messages was 
shown)

Sometimes I also get this message:
[    1.480097] pci 0000:00:04.0: ASPM: Could not configure common clock

Is there anything to worry about, and/or does this qualify as a bug I (sh|
c)ould report?

Kind regards,
Ralf
