Public bug reported: I've reproduced this bug on two systems (same make/model)
I can reproduce this kernel panic by doing the following (from a fresh kubuntu install) 1.) Home directories are NFS-mounted (SSO with kerberos & LDAP) $ apt-get build-dep zeroc-ice $ apt-get source zeroc-ice $ cd zeroc-ice-3.4.2 $ dpkg-buildpackage very shortly after running dpkg-buildpackage (somewhere between the patches being applied to the source and compilation begins (I'm not seeing the typical output of ./configure) the system crashes with a kernel panic. I hooked up a serial cable & dumped the console to it, so I could catch the crash, and the output is below. Additional: I installed http://kernel.ubuntu.com/~kernel- ppa/mainline/v3.6.3-quantal/linux- image-3.6.3-030603-generic_3.6.3-030603.201210211349_amd64.deb (and its headers). The 3.6.3 kernel runs without issues, and I've been unable to reproduce the crash. So it seems likely that the problem is with the 3.5.0-19-generic kernel package.
