>>>** can't synthesize root hub events


The pci_hotplug kernel module talks to userspace /sbin/hotplug, which uses the scripts that are grep'ed below.

I have this message, and it is benign.

Try this:

qaz:~# grep "synthesize pci" /etc/hotplug/*
/etc/hotplug/pci.rc:  echo "** can't synthesize pci hotplug events"
qaz:~#

The solution is in the hotplug init scripts somewhere, though I have not investigated yet myself. If you find anything out, you should post back here.

Two things from make menuconfig: (kernel 2.6.4)


"
CONFIG_HOTPLUG: ?
? ?
? Say Y here if you want to plug devices into your computer while ?
? the system is running, and be able to use them quickly. In many ?
? cases, the devices can likewise be unplugged at any time too. ?
? ?
? One well known example of this is PCMCIA- or PC-cards, credit-card ?
? size devices such as network cards, modems or hard drives which are ?
? plugged into slots found on all modern laptop computers. Another ?
? example, used on modern desktops as well as laptops, is USB. ?
? ?
? Enable HOTPLUG and KMOD, and build a modular kernel. Get agent ?
? software (at <http://linux-hotplug.sourceforge.net/>) and install it. ?
? Then your kernel will automatically call out to a user mode "policy ?
? agent" (/sbin/hotplug) to load modules and set up software needed ?
? to use devices as you hotplug them.

CONFIG_HOTPLUG_PCI: ?
? ?
? Say Y here if you have a motherboard with a PCI Hotplug controller. ?
? This allows you to add and remove PCI cards while the machine is ?
? powered up and running. The file system pcihpfs must be mounted ?
? in order to interact with any PCI Hotplug controllers. ?
? ?
? To compile this driver as a module, choose M here: the ?
? module will be called pci_hotplug. ?
? ?
? When in doubt, say N.
