Over the year I've read some interesting (horrifying?) tales of
debugging on NANOG. It seems I finally have my own to contribute:

http://blog.krisk.org/2013/02/packets-of-death.html

The strangest issue I've experienced, that's for sure.

FWIW, I had a similar situation crop up a couple of years ago with *five
different* Seagate SATA drives: they grew some specific type of bad spot
on the drive which, if you even tried to read it, would *knock the drive
adapter off line until powercycle*; even a reboot didn't clear it.

Nice writeup.

Cheers,
