I am having trouble trying to install version 2.6.15 of the linux kernel onto a machine that is currently running 2.6.9 version of the kernel. I am using the 2.6.9 configuration file and running make install successfully. When I try to boot the new kernel, I get the following: No entry for device mapper found Is device mapper driver missing from kernel? Failure to communicate with kernel mount: error 19 mounting ext3 mount: error 2 mounting none Apparently the device mapper is being used on the current kernel and does exist in the direcotory /sys/misc. What do I need to do to get my new kernel to run? According to what I've read, every kernel since 2.6.9 should have it in the source. I checked the .config file and couldn't find anything called device mapper. There was an entry for an IOMAPPER associated with a certain scsi device that was commented out, but I have no idea what to put after =. I couldn't find a comparable entry using make menuconfig. Any help would be greatly appreciated. I don't really have any need for it so if I can get my kernel to run without it that is an acceptable solution.
