My linode crashed on me again.

This is my third unexpected outage in the 2.7 years I've had it. This time there were no clues as to the reason. The only solution appears to be rebuilding the kernel with KDB, the kernel debugger. If this happens again, I'll be asking linode to provide that.

The first time was a crash, which I was told was related to uml, so I switched to xen. The second time was a raid problem with the host. "We believe this was caused by a flaky drive, which has since been replaced."

I'm very happy with this record.
