There was a problem with diag modules, that were auto-loaded on dump and put some data into uevent sockets thus causing the dump to fail on that socket. The solution that time was to call modprobe in advance to make sure the diag modules are there. This turned out to be not nice solution as modprobe may fail if the module is missing and the requred functionality is built-in. To handle this for diag stuff it is mush faster and more reliable to ping the kernel with simple diag request and check that it reqched the required module.

criu ==== An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space. The project home is at http://criu.org Pages worth starting with are * Kernel configuration, compilation, etc: http://criu.org/Installation * A simple example of usage: http://criu.org/Simple_loop * More sophisticated example with graphical app: http://criu.org/VNC
