Comment 8 for bug 244377

This got not much attention due to other things, sorry about that. Basically the crash results from a sysfs entry that tries to make available more than 4095bytes of data. Unfortunately the handling of it is not very helpful as the crash does not tell which call this was. Upstream had made some changes that would help to debug this. If this is still of interest, I prepared some debug kernels and have placed them to http://people.canonical.com/~smb/lp244377/
With the information those provide we could have a chance to find the real issue. But probably should then open a new bug report. Unfortunately this is a symptom that can be triggered by various drivers.
