Hi folks, I'm getting the following kernel message when I try to run a RAID management tool for the megaraid: ioctl32(megamgr.bin:12688): Unknown cmd fd(3) cmd(c06e6d00){00} arg(080f3f00) on /dev/megadev0 The tool is binary only, and is clearly a 32bit version. My system is a 'AMD Opteron(tm) Processor 246' running kernel 2.6.10-1.771_FC2smp. Am I correct in guessing that some 'stuff' needs to be added to fs/compat_ioctl.c to get this working? If so, how does one tell whether the ioctl needs 32bit <-> 64bit twiddling to work? If anyone has any hints, I might have time to take a look at it. For example, how would I find out how this ioctl gets handled on a 32bit (i386) kernel?
