I was asked earlier for a dmesg dump from when this is triggered. Here it is, but you'll notice that there's nothing there. This is an instantaneous hang for the kernel, so it never has a chance to write anything to the ring buffer, let alone pass that on to log files.
To create this, I ran the following script, appending the output to the file dmesg.log: #!/bin/bash while true; do dmesg -c done sudo ./dmesg-monitor >> dmesg.log ** Attachment added: "dmesg.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/897773/+attachment/2617117/+files/dmesg.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/897773 Title: [Acer AR320 F1 and Acer AR160 F1] Halting shortly after booting with 10.04.3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/897773/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
