I'm still in the progress to find a reliable scenario to produce an UML kernel crash _and_ getting sufficient information. I fear, that the following syslog output (stressed an apache by ~ 3000 http requests and immediately shutdowned the UML) doesn't match the 2nd condition, or ? : Oct 27 20:28:34 n22_uml sshd[1231]:
