Created an attachment (id=73472)
 --> (https://bugzilla.kernel.org/attachment.cgi?id=73472)
complete /var/log/messages for 2 identical shutdowns, different messaging

Full messages might help for these last two, also today o/

Both occurred *exactly* while performing the same task:
* No Flash involved! Just Konsole, Kate and some erroneous Firefox profile,
  which launch locked the CPU every time at 100% - and beyond, said `ps` :)
* My script WAITs were set to 1,1,0,0 (+ 0.5s for cpu % average, still)

Experience was also, exactly the same i.e. Firefox launch, sudden fan max
speed, then very brief OS shutdown screen/console messages, power off.

However, messaging was again, "head or tail":

May 30 16:25:18---21
* My script caught *five* critical events this time (2.5+ seconds), all
complete
* Kernel reported *part* of the ACPI/EC explicit error (cf. previous comment)
* But no "Critical temperature shutdown" message, log was aborted.

May 30 18:02:14
* My script had reported a *unique* (!) "notice" at 74 ÂșC* two minutes before,
  but had cooled back to "yawn" after that (hence looping each 1.5s)
* Kernel reported (part of) the same ACPI/EC error message cf. previous comment
* The "Critical temperature shutdown" message *was* reported, log completed.

So it seems like I can reproduce the issue "at will" and my reports are all
scripted - it's only messaging which is still "head or tail".

Could anyone please guide me any further ?
