Package: memtest86+
Version: 5.01-3
Severity: critical
Justification: breaks the whole system

Hi! There is a situation I belive should be reported ASAP. We have two
Lenovo T500 laptops completely dead after an overnight testing with memtest86+.
Notebooks do not power on, and even do not show up the 'external power' 
ledled when plugging in AC-adapter.

The whole story is:

29-May-2018 Two Lenovo T500 laptops were upgraded with 4Gb memory sticks. After
the upgrade the laptops were powered on with no problems and were used till the
evening.

In the evening 29-May-2018 both laptops were rebooted into Memtest86+ and
set up for an overnight RAM test with default memtest settings.

In the morning 30-May-2018 both laptops where found with a few passes completed
and zero memory errors found. But laptops were not responding to 
keyboard commands. The laptops were turned off with a long press of the power
button and then refused to start.

All the usual tricks were performed including:
- Removing and replacing RAM sticks
- Removing battery and AC power for a period of time
- Ten times and a long press power button advice found on the internet
- CMOS battery removal

Still, two lenovo laptops show no signs of life. We are going to send one
laptop for service today (maybe they would diagnose the issue better), 
but it seems very likely that memtest86+ somehow killed the firmware 
of a motherboard system controller. 

Until the problem is identified, I recommend to issue a warning and (or) prevent
installation/running of the memtest86+ on Lenovo T500 laptops.

Will post updates when more information will be available.
