After updating my FreeBSD 4.7 stable I can't use 2nd network card. It
was possible before update. KERNCONF is the same.
>dmesg | grep ep0
ep0: <3Com 3C509-TPC EtherLink III> at port 0x300-0x30f irq 7 on isa0
ep0: No irq?!
ep0: ep_alloc() failed! (6)
device_probe_and_attach: ep0 attach returned 6
Irq 7 is already taken by
ppc0: <Parallel port> at port 0x378-0x37f irq 7 on isa0
So I booted old kernel:
there were also 2 isa devices on the same irq, bud ep0 was first
and ppc0 didn't complain

I'd like to use both network cards, as you probably guessed.
How would you, Mr. WhoCanHelp, solve this unpleasant situation?
