    Subjectvirt_to_page() with ioremap_nocache -> Ooops
    Hello,

    I have implemented mmap with (nopage), the mmaping consists of normal
    memory from __get_free_pages (set to RESERVED) and some registers/memory
    that are on a PCI card (bar0), i mapped it with ioremap_nocache to to be
    able to read and write it in kernelspace.

    I tried to use virt_to_page(address_from_ioremap_nocache + some_offset)
    and gave this back from the (nopage) function, but this leads to an
    Oops. (with the other memory it works)

    Where is here my error?


    Regards
    Christian Leber
