It is in the journalctl output; Linux version 4.19.0-6-686-pae (debian-ker...@lists.debian.org) (gcc version 8.3.0 (Debian 8.3.0-6)) #1 SMP Debian 4.19.67-2 (2019-08-28) The dell d600 (also failing) uses the non-pae version of it. The functioning vostro uses the same pae-version. What more information can I provide?
