Panic in arpresolve->rt_check?

[Ivan Voras]

Hi,

I've got several crash dumps caused by the following:

Fatal trap 12: page fault while in kernel mode

This is on a recent -CURRENT, i386, SMP. NIC is fxp. If anyone needs 
more data, please let me know - this is a critical problem for me. The 
same machine worked ok with 6-STABLE.
