	If for some reasons the raid configuration information on the harddisk get wired, the raidframe driver
	tries to autoconfigure raid-devices that are not configured in the kernel.
        The kernel variable numraid is set to 4 (as mentioned in the kernel configuration file). This will configure
	4 raidframe devices numbered 0 to 3.
	But in the file rf_netbsdkintf.c for example, valid raid device numbers are checked with '< 0" and '>= numraid'.
	This will accept raid4, but no memory has been allocated for that before ...
	corrupt raidframe autoconfigure information so that raidframe assumes to configure a raid4 device and reboot.
	replace the '>=" by '>' in various places in the raidframe driver sources
