windows 7 iscsi variable boot times - could ixpe be causing it?

If the pc is powered off and on again, the first boot after that will once again be 30s and subsequent 2m (until another power off & on).

Is the link speed (as reported by e.g. the switch LEDs) dropping to 100M for the 2m boots?

With an iSCSI boot, there is no explicit "unload" step. The OS bootloader (bootmgr.exe in the case of Windows 7) simply stops making calls to INT 13.
