I just installed linux-image-2.6.10-5-686-smp and it started OK, but kswapd0 is taking 100% CPU time (which is like 50% total CPU time, cause the box has 2 CPUs).
What does that mean? do I have to worry?
The box has two Pentium III 700 (xeon, I think... they have 1 MB of cache each).

PCI: Using ACPI for IRQ routing
** PCI interrupts are no longer routed automatically. If this
** causes a device to stop working, it is probably because the
** driver failed to call pci_enable_device(). As a temporary
** workaround, the "pci=routeirq" argument restores the old
** behavior. If this argument makes the device work again,
** please email the output of "lspci" to bjorn.helgaas@hp.com
** so I can fix the driver.
