Subject: Re: Linux 2.6.31-rc4: strange change in iomem allocation
I'm seeing the following change in dmesg between -rc3 and -rc4:
-system 00:0c: iomem range 0xfec00000-0xfec000ff has been reserved
+system 00:0c: iomem range 0xfec00000-0xfec000ff could not be reserved
There is nothing in the earlier part of dmesg that would explain this
change.
The change is also visible in /proc/iomem:
fec00000-fec00fff : IOAPIC 0
fec00000-fec00fff : reserved
- fec00000-fec000ff : pnp 00:0c
I somewhat suspect 857fdc53a0a90c3ba7fcf5b1fb4c7a62ae03cf82:
x86/pci: insert ioapic resource before assigning unassigned resources
System is HP 2510p notebook (x86_64).
Cheers,
FJP
