Doing some more playing around and it locks up with 6 disks too, just a few seconds later, during the initialisation of the array. When trying with 8 disks results in the following strace (hand copied): open("/dev/md/0", O_RDWR) = 4 ioctl(4,0x400x0930,0xbffff650) = -1 ENOSYS ioctl(4,0x400x0930,0xbffff650) = -1 ENOSYS ioctl(4,0x400x0930,0xbffff650) = -1 ENOSYS ioctl(4,0x400x0930,0xbffff650) = -1 ENOSYS ioctl(4,0x400x0930 And there it stops. Seven disks gives a lockup immediately upon completing the mkraid command. Six locks up about 1-2 seconds later (enough time for me to initially think it was working and run a raidstop :<). I'm doing a fresh kernel build incase it's a feature of the Mandrake 8.2 kernel. If that fails I'll try with different numbers of disks until I get something that works... Thanks.
