I went ahead and ran apt install mcelog, i'll provide logs the next system freeze that occurs. I have the original posters identical 2-1 toshiba laptop, identical model number and part number and experiencing these identical exact issues and symptoms.
Sensors doesn't seem to be able to detect the fan, but does report CPU temps, but i don't see it going over 60 deg C, .... Web browsers with multiple tabs open seem to force the freeze much faster.. but just idling at the desktop, with a terminal window open causes the freezes as well. small work around that seems to make the freeze happen far less frequent is to set temp trigger points that when the CPU temp reaches 55 degrees C, I use tlp to lower the CPU speed down to its minimum of 500mhz from its peak of 2.6ghz (in turbo), and 2.16ghz in normal clock speed. I believe its temp related, as it doesn't freeze nearly as often when the AC is unplugged, and with the battery charging/ac plugged in the temps start to rise quickly. None of these freezes/heat issues/fan detection issues occur in Windows, but I'd really like to remove that OS asap, and use Ubuntu exclusively. toshset is a package that is supposed to allow control over various non- legacy bios Toshiba laptops by using ACPI entirely, including fan, bluetooth but the app kicks out the error "required kernel toshiba support not enabled" and that's with toshiba-wmi and toshiba_acpi modules loaded. (i can try to recompile the kernel with these hardcoded, but i'd rather not recompile the kernel every time i update) I have been troubleshooting the issue since purchasing the device in Feb '16... I have installed various versions of Ubuntu (14.04lts, 14.10, 15.04lts, 15.10, and now 16.04lts), and have installed various kernels, including new branches 4.6.3 and 4.7 trying to find an end to the lockups. (sysreq REISUB does not work, these are an entire system hard freeze) i have done the dsdt walkthroughs i found elsewhere on the web to pull as much info from the bios of the system, which created several files: dsdt.dat/dsdt.dsl and all the subsequent ssdt*.dat/ssdt*.dsl files, if those would help at all. Let me know what you need, I'm highly motivated to get this issue resolved, as its been frustrating me for months. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1546092 Title: computer freezes frequently Status in linux package in Ubuntu: Won't Fix Status in linux source package in Xenial: Won't Fix Bug description: Running Xenial.
