Hi together, so some updates to this issue, after disabling the ppb_hotplug_remove() function, I could prevent the kernel panic. Now I can see that em1 dies. After a ifconfig down/up I get the following message:
em1: The EEPROM Checksum Is Not Valid em1: Unable to initialize the hardware Any ideas, why this could happen? How can I debug this deeper? At the moment I have done a pcidump -xxx on a good state and would repeat this if the network dies the next time. I also activate "ifconfig em1 debug". Could it be a driver bug or maybe a hardware failure? Some strange power saving failure? At the moment it could be anything I know ;-) nice regards, Sebastian
