Hi Frank,
this change breaks the network on my macppc, with r1.93 it only seems to be
able to send packets, but never receives answers (ARP does not complete,
but other hosts see the ARP requests).
gem0 at pci2 dev 15 function 0: Apple Computer GMAC Ethernet (rev. 0x01)
gem0: interrupting at irq 41
brgphy0 at gem0 phy 0: BCM5411 1000BASE-T media interface, rev. 1
brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT,
1000baseT-FDX, auto
gem0: Ethernet address 00:03:93:71:ff:cc, 10KB RX fifo, 4KB TX fifo
It is connected to a gige switch:
media: Ethernet autoselect (1000baseT full-duplex,master)
status: active
(which looks the same in the non-working kernel).
Any ideas how to debug?
Martin
