So the memory at d094ee7c (which contains i810fb's pci table) became unmapped from kernel virtual address space as a result of you inserting your carbus card. I am impressed. Jsut as a crazy test, could you delete /sbin/rmmod and see if it still happens? Maybe something is removing the module at an embarrassing time or something. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
