I can't help you but I can confirm that I had similar problems with
CURRENT some time ago. I'm quite sure my problems were related to
pppoe(4) since it never happened again after switching back to pppoe(8).
My DSL provider disconnects my link every 24 hours -- the crashes didn't
happen at every disconnect, but when the box crashed it was always at
these times.
I don't know if it helps, but after one of these crashes, I gathered the
following output:
