Errors in DMESG

[triad]

1st off New Ubuntu user here and I must say I am very impressed so
far.  Still have gentoo loaded on main partition but might migrate
soon if I can get a handle on Ubuntu.  Now onto my question:

I am getting a few errors during Ubuntu bootup that are driving me up
the wall. I have attached my dmesg output and the The following
highlights the errors I am getting:

PCI: Cannot allocate resource region 4 of device 0000:00:02.1
VFS: Can't find ext3 filesystem on dev hda1.
VFS: Can't find ext2 filesystem on dev hda1.
VFS: Can't find a valid FAT filesystem on dev hda1.
shpchp: acpi_shpchprm:\_SB_.PCI0 evaluate _BBN fail=0x5
shpchp: acpi_shpchprm:get_device PCI ROOT HID fail=0x5
pciehp: acpi_pciehprm:\_SB_.PCI0 evaluate _BBN fail=0x5
pciehp: acpi_pciehprm:get_device PCI ROOT HID fail=0x5
nfs warning: mount version older than kernel
APIC error on CPU0: 00(02)

Some info:

hda1 is where Ubuntu is installed on and it is reiserfs.
I am running kernel 2.6.8.1-3-k7

Any help would be greatly appreciated.  If you require any further
information let me know.
