Bug Description
I had some problems resuming from suspend with my MSI Wind U100. It seemed to power up, but all I got was a blank screen. Sometimes, I would get 2-3 seconds when I could move the mouse around OK, but then it would inevitably freeze and I'd be forced to hard-reset the machine by physically powering it off. It would be completely unresponsive to any keyboard or trackpad commands, including switching to other terminals (ctrl+alt+f1, etc). Interestingly, this would only happen when I was running on battery power. On AC power, suspend and resume worked fine, but once I was on battery power, my laptop would freeze upon resume and I'd be forced to hard-reset. Even more interestingly, I could suspend and resume fine on AC power, but then once I unplugged the power cord, the computer would immediately freeze again.
After reading a post on ubuntuforums (http://
WORKAROUND: So then I edited /etc/pm/
So I'm not sure how to pinpoint the exact problem, but according to my experience and the forum posters' experiences, this has only been a problem since Maverick. It may be as recent as the latest kernel update, but no older than the kernel update that came with 10.10. So it might be a problem with the new kernel and the r8187se module, or it might be a problem with something else about the way these computers suspend and resume.

This could be a duplicate of bug 663784; there's a workaround described there. I think the common factor might be the r8187se module. Could you please try the workaround and report if it works for you?
