Similar case with a Shuttle B52G barebone when connected via the fxp0 port of the Shuttle. em0 of the Shuttle port worked. >Description: System hangs during boot after or during loading the kernel from disk and before displaying the "Options Menue", where one is asked for "boot without ACPI" etc. when the system is connected to the ethernet during bootup. We experimented with ACPI disabling in the BIOS setup or with disabling USB in the BIOS setup. >How-To-Repeat: Boot the system while ethernet connection to a cisco-2950 is plugged in. In approx. 15-30% of the cases the system will hang after or during reading the kernel from the harddisk. >Fix: Work-Around: - simple: unplug the powercord, plug the power back in, reboot does not always work around the problem - complex: unplug the powercord, unplug the ethernet (!), wait a few seconds, plug the power back in, reboot >Release-Note: >Audit-Trail: >Unformatted:
