PCI
- pci=off Don't use PCI
- pci=conf1 Use conf1 access.
- pci=conf2 Use conf2 access.
- pci=rom Assign ROMs.
- pci=assign-busses Assign busses
- pci=irqmask=MASK Set PCI interrupt mask to MASK
- pci=lastbus=NUMBER Scan upto NUMBER busses, no matter what the mptable says.

Debugging
- oops=panic Always panic on oopses. Default is to just kill the process,
- but there is a small probability of deadlocking the machine.
- This will also cause panics on machine check exceptions.
- Useful together with panic=30 to trigger a reboot.
-
kstack=N Print N words from the kernel stack in oops dumps.
pagefaulttrace Dump all page faults. Only useful for extreme debugging
