@Brad: I tried 3 of the mainline kernels from around the time the freezes started to happen. None of the mainline kernels fully boot the machine, making it impossible to test the bug. I can get to a VT if I disable the vt.handoff, quiet, and splash kernel parameters. From there I can see that a number of modprobe calls are stuck in uninterruptable I/O wait. Commands like 'lsmod' do not return either.
I observed this behavior with each of these kernels: linux-image-3.2.0-030200-generic 3.2.0-030200.201201042035 linux-image-3.2.1-030201-generic 3.2.1-030201.201201121644 linux-image-3.2.2-030202-generic 3.2.2-030202.201201252035 I'll try some newer mainline kernels as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/929111 Title: Repeated freezes when running on battery power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/929111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
