Re: hotplug error at boot time
** 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.
