Bug Description
was using vim on tty1;
calling "sync" every 10s using infinite for loop on tty2 (minimise data loss due to system crash on ext4 partition)
kernel messages pops up over my vim screen, but system kept running with no observable problem under either active tty.
system hangs when trying to switch to gui (Ctrl-alt-F7) - blank screen, system not responding to magic sysrq.
ProblemType: KernelOops
Annotation: Your system might become unstable now and might need to be restarted.

Hi Quincy,
This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http:// cdimage. ubuntu. com/releases/ .
If it remains an issue, could you run the following command from a Terminal (Applications- >Accessories- >Terminal) . It will automatically gather and attach updated debug information to this report.
apport-collect -p linux 457745
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
