Firstly, I get that EEPROM problem whenever the cardbus bridge is enabled. Disabling cardbus made that particular problem go away completely. However I still had problems with suspend/resume and I submitted a PR/patch that fixes it on my machine: http://www.freebsd.org/cgi/query-pr.cgi?pr=i386/59806 Perhaps the two problems are related? My problem with suspend/resume can also be said to happen "often" but not always. When em0 dies I tend to get watchdog warnings, and often even a kernel panic as mentioned in the PR. (I'm thinking perhaps the two problems are caused by the same thing but result in different error messages in our two situations.) -- / Peter Schuller, InfiDyne Technologies HB PGP userID: 0xE9758B7D or 'Peter Schuller ' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org
