Message-ID: <9fa5f2891003122017x72c92682md32c62e272f64380@mail.gmail.com> Date: Fri, 12 Mar 2010 23:17:35 -0500 From: Alexei Colin <acolin10@...lege.harvard.edu> To: netdev@...r.kernel.org Subject: sungem on PowerMac G4: RX MAC fifo overflow Hi, Any help on this issue would be greatly appreciated. I am emailing netdev because I couldn't find anything relevant online (except ancient inconclusive reports of the same error message). Issue: system loses Ethernet connectivity after several hours usually or sooner occasionally. This message gets written to the log multiple times: eht0: RX MAC fifo overflow smac[<a mem address>] Machine: PowerMac G4 (no more firmware updates applicable) Ethernet: 0002:20:0f.0 Ethernet controller: Apple Computer Inc. UniNorth GMAC (Sun GEM) (rev 01) System: Linux 2.6.31-19-powerpc #56-Ubuntu Thu Jan 28 00:50:48 UTC 2010 GNU/Linux Driver: sungem (srcversion: 9C4DDFB8D2201E852413F4F) I'd like to think that it started after I updated to Ubuntu 9.10 (different version of sungem), but booting into 2.6.28-6-powerpc (after the dist upgrade, though) the same is observed. This does bring back the network: ifdown eth0; rmmod sungem; modprobe sungem; ifup eth0 (I never tried without reloading the module) Please let me know if you would like me to get debugging info and which. Thank you in advance!
