Comment 29 for bug 528981

I am having the same (read-only file system) problem after wake from sleep triggered by opening the lid on the laptop. I have included all the useful information I gathered from logs. I will also, as previously described, attempt to capture more relevant data if/when phenomenon occurs again.
