Hello, all: I compile my linux module program dony.c with "-D--Kernel__ -DMODULE" options enabled, and then insert it into kernel using "insmod dony.o" . It stops when it tries to access a global varible "struct dony_struct MyPrivateStruct" and complains such messages as "cannot handle page request at virtual address 0xdXXXXXXX". So I printk its address and find it is at 0xdXXXXXXX instead of 0xcXXXXXXX. How can I solve it? Thank you very much. dony PS: I have not joined this mail list yet.
