Can't load new modules/driver due to "Exec format error" / "Skipping invalid relocation target"
Hi all,
I'm trying to update the driver for our Intel C62x Chipset QuickAssist Technology add-on card, but getting the mentioned errors when I try to load the modules. I haven't done this in a while, but I thought the process was pretty straightforward:
1. Stop the QAT services [ ok ]
2. `uninstall` the QAT driver [ ok ]
3. `modprobe -r` any remaining QAT modules [ ok ]
4. download, extract, `configure`, `make` the new QAT driver [ ok ]
5. `install` the new driver [ FAIL ]
For example:
# make -j16 install
[...]
make -C /lib/modules/4.19.0-5-amd64/build M=/usr/local/src/QAT.L.4.20.0-00001/quickassist/qat INSTALL_MOD_DIR=updates modules_install

Meanwhile, the system log shows:

What are these errors even talking about and what is the cause and possible solutions?
Thanks so much!
