My guess there is that it is a 68k problem, as it seems that running one ppc
prog with normal priority, and one with an abosolute minimum in priority,
makes the risk of crashing very small. That's why it does not crash with
dnet running. It therefore seems to be the 68k handling the PPC priorties
wrong. Still I know shit about stuff like the software on PPC and 68k, so
I'm just guessing.
BTW: you doodz that are using dnet, I have a problem, each time a block is
done, it writes or loads and stuff the buffer using 98% of my 68k... with
something like priority +100, it's a pain in the ass, a few seconds every 5
minutes or so, with everything being handled as slow as if it was a
68000@5MHz. How do I set harddisk reading and writing to a lower priority,
global and for single program?

Hmm, hvad do you mean by somewhere near the PPC board?
Do you mean those oscillator chrystals that are about 1.5 the length and the
same width of those on the PPC board? You can mount this almost on the spot
where the crystal is meant to be, but on the other side of the board, with
two wires connecting the two pins that don't fit in. It's no big deal how
big the osc is, as long as it isn't one of these huge variable lab thingies
using power from the net :)
Yup, I could get ya one, what frequency do you need? What frequency is your
current oscillator at?
