6.5.13-3-pve kernel panic on shutdown

[Stefan Radman]

I recently noticed that a Dell Poweredge R540 currently running Proxmox VE 8.1.8 (kernel 6.5.13-3-pve) throws a kernel panic on shutdown.

The kernel panic is triggered 3-4 seconds after the last network interface goes down (onboard BCM5720 LOM), while the system enters S5 (sleep) state.

This is reproducible on every reboot.

R540 and BCM5720 are running the latest firmware available from the Dell support website.

Link [2] below seem to suggest that my problem is related to a combination of ACPI S5, the tg3 driver and the BCM5720 on-board NIC.

Has anyone else seen this lately (or ever) with Promox VE?

Thank you

Stefan
