To fix this bug, we need to know how to determine if a laptop computer will support hotplug or not, and correct the pci_hotplug hotplug detection. -- PCI ExpressCard hotplug requires pciehp.pciehp_force=1 https://bugs.launchpad.net/bugs/371434 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
