Not sure about the other parts, but:
6.7.12-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.7.12-1 (2024-04-24) x86_64 GNU/Linux.
Is not a real time kernel.
( It needs to say "PREEMPT_RT" )
6.7.12-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.7.12-1 (2024-04-24) x86_64 GNU/Linux.

Almost 3 years later and I still have hm2/hm2_7i96s.0:error finishing read!
Grub quiet isolcpus=11 idle=poll r8168.EEE=0 pcie_aspm=off
john@cave:~$ sudo ethtool -i enp6s0
[sudo] password for john:
driver: r8169
version: 6.1.0-29-rt-amd64
firmware-version: rtl8168e-3_0.0.4 03/27/12
expansion-rom-version:
bus-info: 0000:06:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no
john@cave:~$ uname -a
Linux cave 6.1.0-29-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.123-1 (2025-01-02) x86_64 GNU/Linux
The r8168-dkms network driver is installed but ethtool reports the driver as r8169
This package provides the dkms source code for the r8168 kernel modules.
Kernel source or headers are required to compile these modules.
Is the above line from apt my clue?

You can temporarily check if this helps:
first
chmod +x pinirq.txt
then
sudo ./pinirq.txt [ethernet_device_name_]
Where [ethernet_device_name] is the name of the Ethernet device connected to the 7I96S
(probably eth0, eno1 enp0s25 or similar)

The problem that is fixed by the DKMS driver has fairly specific symptoms.
can you run:
sudo chrt 99 ping -i .001 -c 60000 -q 10.10.10.10
(will run for ~ 1 minute)
and post the stats here
(assuming 10.10.10.10 card address)

dkms builds the drivers from source so you need linux-headers installed for the kernel version you are using. but first you need to
sudo apt purge r8168-dkms
then reboot, then
sudo apt install linux-headers-$(uname -r)
sudo apt install r8168-dkms
sudo apt purge r8168-dkms
then reboot, then
sudo apt install linux-headers-$(uname -r)
sudo apt install r8168-dkms

It happens, sorry I broke it... sometimes you can log in using another kernel on your system and resolve. I just can't remember how but I have been caught a few times...
