I'm quite certainly missing something completely obvious here, but how
can you get the WS1 interrupt *after* raising a panic? Aren't all
interrupts disabled and the system fully halted once you get a panic(),
especially when raised from an interrupt handler? If that's the case,
how can the system continue to do things, such as receiving the WS1
interrupt and resetting ?
Again, I'm probably missing something obvious, but I'm interested to
understand the reasoning here.
Thanks!
Thomas
