It would be even more interesting if you have a serial console, but if this is the X server stomping on the PCI bus, you might just have a total lockup - no oops, no nothing. One thing that might be interesting is to see if the old working kernel has a different IO-map than the broken ones. A simple cat /proc/ioports /proc/iomem > iomaps.kernel-version and diffing the two might be an interesting thing to try. X has been known to sometimes just try to re-configure things on its own without telling (or asking) the kernel. Linus
