The big thing that jumps out at me is the following from dmesg:
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
PCI_IDE: unknown IDE controller on PCI bus 00 device f9, VID=8086, DID=24db
PCI: Device 00:1f.1 not available because of resource collisions
PCI_IDE: BIOS setup was incomplete.
PCI_IDE: chipset revision 2
PCI_IDE: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x1880-0x1887, BIOS settings: hda:pio, hdb:pio
ide1: BM-DMA at 0x1888-0x188f, BIOS settings: hdc:pio, hdd:pio
The system doesn't know what kind of ide controller you have and isn't
enabling dma for your ide drives.
Additionally, the following error seems to be related.
Dec 4 10:46:25 machine blk: queue c01c6e24, I/O limit 4095Mb (mask 0xffffffff)
Dec 4 10:46:25 machine ide0: unexpected interrupt, status=0x58, count=1
A quick google search on "unknown IDE controller on PCI bus 00 device
f9, VID=8086, DID=24db" and " machine blk: queue I/O limit 4095Mb (mask
0xffffffff)" Seemed to indicate turning off APIC support in the kernel
or upgrading to a 2.5/2.6 kernel.
Since you have a SMP system, in order to turn off APIC, you will need to
pass noapic as a kernel parameter in your grub.conf or lilo.conf file.
