Q: Has this system ever had any prior Ubuntu releases installed on it, or is Trusty the first? A: This system has had Saucy installed on it but the installation to Trusty was fresh (drives wiped). The behavior described did not occur under Saucy
Q: Can you also see if this issue happens while the system is connected to AC power for 24 hours? A: I have tested this with the system connected to AC and it does occur. Q: There are a couple of initial triaging steps we can perform. One would be to test the latest mainline kernel to see if this bug is already fixed upstream. If it is not, we should also find out if this is a regression. If it is a regression, we can bisect to find the commit that introduced this. So in addition to testing this bug with AC power, can you also test the latest mainline kernel, which can be downloaded from: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc5-utopic/ Just let me know if you have any issues or questions installing that kernel. A: Haven't done this but will over the weekend. I see the note regarding the outdated bios and will also test that (upstream kernel first, see if it recurs; upstream and stock kernel using new bios as well). Q: Can you review your BIOS settings to see if there is an automatic wakeup set there? A: There is not. Q: Also, is the system waking up 24 hours from the time it is suspended, or does it wakeup at the same time of day? Just trying to see if an external USB device is waking it at a specific time. A: The system will wake up 24 hours from the time suspended regardless of time of day. Q: One last thing, the Firmware Test Suite can dump some CMOS data to see if wakeup is set. If possible, can you install fwts and run the following: sudo fwts cmosdump Then attach the output.
