Hm, I'm not sure if something is changed between the different kernel versions, but I compiled the module under 2.6.34. All I did was 'make', and it generated the acpi_call.ko file, which I could 'insmod' later. >From the error log, I can see that it doesn't know the copy_from_user function, maybe try inserting '#include <linux/kernel.h>' or something similar in the beginning. I will try it out once I get to my machine. _______________________________________________ Mailing list: https://launchpad.net/~hybrid-graphics-linux Post to : [email protected] Unsubscribe : https://launchpad.net/~hybrid-graphics-linux More help : https://help.launchpad.net/ListHelp
