Since it&#x27;s a debug log from the kernel, it makes sense to take the time to make sure it gets all the way to the disk. For many other purposes, it&#x27;s fine to be quick and just do the best effort. But the kernel log is a vital resource for doing post mortem analysis if everything goes wrong and the kernel panics.<p>It&#x27;s better to be slow than unreliable in this case.
