I'm getting a kernel panic on the 2.6.11 code from user-mode-linux.sf.net. Details: host=2.6.8.1+skas3v8. guest = 2.6.11 plus the 2.6.11-rc3-mm2 tarball from user-mode-linux.sf.net minus x11-fb, cross-build (in order to get past a compile error). The panic happens when starting up a Java process (specifically starting up tomcat). The problem does not occur with a vanilla 2.6.11 guest. I'm happy to carry on using vanilla 2.6.11. But hopefully the stack trace below triggers some insight into a problem with one of the latest uml.sf.net patches.
