Kernel crash

[Melroy vd Berg]

Dmesg kernel crash using OPNsense 24.10.1 Business (fully up to date). I use both IPv4 and IPv6 (dual stack), nothing special about my setup and no additional package installed. And using the official Deciso hardware:

It looks like you've triggered a bug in the axgbe NIC driver. The stack trace shows that the function "axgbe_isc_rxd_available()" triggered a kernel mode page fault. Since the memory page does not exist, this usually indicates an invalid memory pointer.

Solutions could be waiting for an update of that driver (axgbe) or changing the NIC.

[Melroy vd Berg]

Thanks. Changing the NIC? I'm using official Deciso hardware: DEC3852...?
