** Description changed: Using Ubuntu 9.04 Jaunty as a reference, hotplugging an expresscard does not work on my Dell Inspiron 1420n laptop computer. I can add "pciehp.pciehp_force=1" to the kernel cmdline options and then hotplugging will work. The tested device is a StarTech EC1394B expresscard. A) Scenario pciehp.pciehp_force=1 and the expresscard absent at boot time *A1.
