    I'm fairly sure this is not specific to -mm2 since it looks
    at lot like my problem from plain 2.5.49
    (http://marc.theaimsgroup.com/?l=linux-kernel&m=103805691602076&w=2)
    but -mm2 gave me some usable debug output:

    Debug: Sleeping function called from illegal context at include/
    linux/rwsem.h:66
    Call Trace: __might_sleep+0x54/0x58
    sys_mprotect+0x97/0x22b
    syscall_call+0x7/0xb

    Unable to handle kernel paging request at virtual address 4001360c

    (I did not copy the rest but can reproduce at will.)

    AFAICS, the fingered function is down_write at mprotect.c:262
    but I fail to see why it is in a illegal context...

    Hope this is useful for somebody. I am willing to test patches.

    Regards,
