This morning, when I checked the available updates in the update manager, I found a new kernel waiting to be installed. I upgraded to this kernel (version 3.0.0-17.30) and successfully booted into it with no problems.
william@ishtar:~$ uname -a Linux ishtar 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 17:34:21 UTC 2012 i686 i686 i386 GNU/Linux After I booted into this kernel, I found that I was able to make big disk image files with both the qemu-img command and through the VirtualBox GUI. I was also able to interrupt the file creation process with ctl-c in the command window, or by pressing the cancel button in VirtualBox. This issue seems to be fixed with this new kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925309 Title: unkillable process consuming 100% cpu time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/925309/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
