Content-Type: text/plain; charset=iso-8859-1 Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: Hi, I just upgraded to LinuxPPC R5 from something that approximates R3. (Kernel 2.1.24) I didn't really upgrade, but more start from scratch. The builtin ethernet card (MACE as you know) was working fine before the upgrade since I did a backup over the LAN to my main Intel linux box before the upgrade. I wasn't able to use NFS or FTP for the upgrade, but resort to a CDROM install. After the install, I realized that the ethernet card wasn't working properly. DHCP works fine but nothing else works. If can grab an IP any time I want with pump, but ping doesn't work. If I look at ifconfig, I see that there are a lot of dropped packets plus some errors and some frames errors. I tried this with kernel 2.2.6 and 2.2.12 both with booting with Open Firmware or booting with BootX. I have no networking problem in MacOS. One other person has contacted me with an identical problem. I also know that the card transmits the packets fine since I see them reach the Intel box when I run tcpdump on that one. So it seems like its a receive problem. I looked into the MACE driver source code, but there is not any changelog, so I have no clue as where this may have break. Does anyone knows what have changed between 2.1.24 and 2.2.X in the MACE driver (or in other part of the kernel) that may have broken the receive part of the driver. I am willing to help debug this driver, but I will need some pointer and clue since I am no expert kernel hacker. And I am much less familiar with the PPC port. Where do I start to look ? Thanks for your insights. P.S. Since I am not subscribed to the linuxppc-dev list, could you please CC me replies. -- Francis J. Lacoste iNsu Innovations Inc.
