Package: linux-image-5.10.0-18-amd64 Version: 5.10.0-18-amd64 Problem: The system cannot reboot anymore because the kernel has a problem unloading the coprocessor driver. Intel Atom Processor (Coprocessor) driver C3758 / C3xxx Reproducible: yes (fresh Debian debian-11.5.0-amd64-DVD-1.iso installation) My motherboard is a MBN802 (you can search the specs with your favourite search engine if you like). After first installation i get: [ 6.891481] c3xxx 0000:01:00.0: Failed to load MMP firmware qat_c3xxx_mmp.bin [ 6.898666] c3xxx 0000:01:00.0: Failed to load acceleration FW To install this drivers i have to install them with: cd /lib/firmware wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/qat_c3xxx.bin wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/qat_c3xxx_mmp.bin After rebooting i can see them with: modprobe -D qat_c3xxx insmod /lib/modules/5.10.0-18-amd64/kernel/crypto/authenc.ko insmod /lib/modules/5.10.0-18-amd64/kernel/drivers/crypto/qat/qat_common/intel_qat.ko insmod /lib/modules/5.10.0-18-amd64/kernel/drivers/crypto/qat/qat_c3xxx/qat_c3xxx.ko If i unload it manually i get "kernel tainted" and the system crashes: modprobe --remove-dependencies -f qat_c3xxx [ 343.834657] qat_c3xxx: module_layout: kernel tainted. My temporary solution is: Switch to Liquorix kernel. With kernel 5.19.0-9.1-liquorix-amd64 the drivers are running fine. See howto at: https://www.linuxcapable.com/how-to-install-liquorix-linux-kernel-on-debian-11-bullseye/ Maybe you can fix this bug in future versions and compare the difference between the Liquorix and actual Debian kernel. Thanks. Christian
