Comment 39 for bug 775950

I have the same exact problem on a sony vaio with a fresh wubi installation of ubuntu. The AC power seems to play a critical role on the occurrence of the error but also experienced the error every time there was a first run for the kernel i.e. after wubi finished installing i got the error, then powered off and on again and it was fine, then i was prompted about updates and after i restarted again to load with a new kernel i got the message again.
