I'm having difficulty accessing the memory on a PCI adapter I'm writing a driver for. I map the memory with pci_map_mem and am using the pointer returned to me in the va parameter. When I try to to write the memory, what I read back is not the same. I'm using copyin/copyout to write/read the memory from buffers passed from user space. Also, if I try to access the memory on the board directly (ie with a printf) the machine locks up. Does anyone have any ideas what may be wrong.
