Bug#990642: linux-image-4.19.0-17-amd64: kernel panic on xen dom0 with Broadcom Limited NetXtreme II BCM5709

[spi]

So, did some more testing.

1) Tried two different ports for binding interface on the 4-port-NIC:
again kernel panic

2) Compiled mainline 5.14-rc1 (2021-07-11) kernel from kernel.org: again
kernel panic with either two ports on the 4-port-NIC


3) Added another 2-port-NIC into server:
06:01.0 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet
Controller (Copper) (rev 03)

06:01.1 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet
Controller (Copper) (rev 03)

driver: e1000
version: 7.3.21-k8-NAPI


When configuring a two port bonding interface on this Intel NIC there is
no kernel panic neither with 5.14-rc1 nor 4.19.0-17-amd64.


For me it seems there is an issue with the bnx2 driver used for the
Broadcom Limited NetXtreme II BCM5709 Gigabit Ethernet (rev 20).
