I seem to have a somewhat different problem, and it happens with almost all distros i've tried. The following is a screenshot from Fedora 3 (PCQLinux). In ubuntu, the last thing i see is
"Mounting Hotplug Subsystem"
Mandrake 10.1 hangs as soon as the blue install screen comes up. I've tried running the system on just internal gfx (empty PCI & AGP), but to no avail. Please help. And sorry if i've posted in the wrong place.
