About month ago after one of my amd64 8-CURRENT upgrade I have started to see crashes with very strange message: Fatal trap 30: reserved (unknown) fault while in kernel mode Crash usually happens during some driver loading or unloading, for example, snd_hda, which always worked fine before, or during ata channel detach/attach which also causes device destruction/creation. Backtrace of this state shows nothing interesting, for example idling in acpi_cpu_c1() or just DELAY(). Does anybody knows, for whom is this fault "reserved" and what does it mean? -- Alexander Motin
