Comment 206 for bug 987220

Judging by the number of different architectures affected, I speculate that bug occurs on a specific class of hardware (specific set of motherboard chipsets?)

I have had this same (or similar?) issue plaguing two of my desktop machines out of three. All have Ubuntu 15.04 currently on all three, all three have similar hardware configurations and the same M/B vendor, yet different motherboards.

What I would like to know is, specifically with what hardware components could shutting down become an issue? How would I find out which one I have (maybe, specific entries in output of "lspci", something in the kernel log, etc.)? How do I determine whether two of my machines are suffering from this same bug or a different one?

-Thanks
