I can confirm that reverting commit e587cadd8f47e202a30712e2906a65a0606d5865 (as pointed out in the upstream bug report) fixes the problem for me, in Mandriva.
It is also important to say that I have ran git bisect between versions 2.6.25 and 2.6.26-rc1 (see comment #73) and it confirms that the commit above is the culprit. I will also revert that commit from latest 2.6.27-rc3 just to be sure that it really fixes the problem. Now the hard part: we have to investigate whether this is a kernel bug (which, for some reason only happens on virtualbox) or whether it is a virtualbox bug. -- Kernel panic during boot in VirtualBox with kernel 2.6.26.*-generic https://bugs.launchpad.net/bugs/246067 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
