I've seen the 'scheduling while atomic' panic message a few times
from the linux kernel over the years, and now I'm wondering if there
is an analogous panic in the BSD kernels, DF in particular.
If so, what would trigger such an event?
I'm certainly not one of the smart people but I do believe (from the
name) that such a panic would occur if trying to call the scheduler
while performing an atomic operation (being inside a critical section).
The reason that this causes a panic would be that scheduling is not a
quick operation (not atomic-quick anyway).
As to whether this can happen in DF or not I don't know, but it sure
sound like something that should panic the kernel. If there is code that
will cause such a panic is another question.
