I had the same problem, for just about any Ubuntu version I tried (dapper, edgy, feisty) and a range of kernels (generic and custom). Also I used to have the same problem in Gentoo aswell.
The ibm-script I'm referring to can be found at the above link or, more exactly, here: http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-67166 Try this if nothing else works for you. Beware that this may break you ethernet card, or your system, or both, or maybe the earth will explode. Uh, that'd be inconvenient. Don't blow up the earth, please. # Remove module if it was loaded. sudo modprobe -r e1000 # Re-load it ignoring invalid EEPROM checksum. sudo modprobe e1000 eeprom_bad_csum_allow=1 # Run the ibm script on the respective interface; for me it was eth0. sudo ./vidalia-eeprom-mod-script eth0 # Reboot. sudo reboot -- e1000 EEPROM Checksum validity check should be disabled https://bugs.launchpad.net/bugs/60388 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
