Hi,

I just lost a couple days of my life!

The colony 3 cd fails to start on my new Dell Precision 380. It gets to starting
the hotplug system, into usb.rc, then just hangs. I disabled USB in the bios,
booted with a ps2 keyboard, and that worked. But then you are left with a system
that hangs in hotplug when you start USB.

The issue is that the intiramfs is traversing /sys and loading up modules for
the devices. For some reason it is loading uhci-hcd for the usb bus when it
should be loading ehci-hcd.

This is as noted in bug #12247 and in
http://lists.us.dell.com/pipermail/linux-precision/2005-August/000626.html. Bug
#12247 is actually a symptom of this bug.

The workaround is to edit /etc/mkinitramfs/modules and add one line "ehci-hcd",
to the end. Not sure how the installer should deal with this -- is there an
option to load certain modules first? This might be a bios bug, but it should be
possible to work around it. Now I have everything working. On my nice new system
:) But those two days will not come back to me.

Also note that FC4 installs fine.
