[PVE-User] 6.5.13-3-pve kernel panic on shutdown

Workaround: No more kernel panics on reboot when pinning kernel 6.2.16-20-pve.

Affected kernels:
6.5.13-1-pve
6.5.13-3-pve

The original issue [1] was solved long ago [2] but apparently re-introduced recently [3].

Regression [4] being discussed on kernel.org

Looks like a back and forth in the tg3 driver.

Note that the kernel panic is only triggered by “reboot” and not by “shutdown”.
