Arresti anomali del kernel nel server Red Hat Enterprise Linux

Installazione sui seguenti componenti:

1. PowerPath versione 6.4
2. Sistema operativo: Build Oracle del kernel Red Hat Enterprise Linux 7.5 di Red Hat Enterprise Linux 7.5 3.10.0-862.3.2el7.x86_64
3. VCS: VRTSvxfs-7.4.0.1200
4. Infoscale 7.4

Configurazione:
SW DELL: PowerPath per Linux 6.4
OS: Software Red Hat Enterprise Linux 7.5
non DELL: VRTSvxfs-7.4.0.1200
SW non DELL: Infoscale 7.4

Il server si arresta in modo anomalo al riavvio con:
