Package: src:linux
Version: 4.19.67-2+deb10u1
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

   My notebook type is:IBM ThinkPad R50e, model 1834LC4.

When I use the command: cat /proc/acpi/ibm/video ,my computer will dead,
no any error info display on screen,network is can't ping,keyboard no response.
no any error log in /var/log/* .

I think my notebook is dead.
