I got the driver working(both gst-launch and v4l2-relayd) as per comment #48 (comment) with arch linux on kernel 6.0.9.

Unfortunately laptop started to freeze when tried suspend/hibernate. dmesg/journalctl output is empty. After deleting drivers everything works normally.

I tried to compile newer kernels 6.1.7 and 6.2.2 and driver doesn't work(problems with mainline ov2740, I hope the fix is described here #55 (comment) but haven't tried) but the suspend/hibernate issue persists even with camera not working. The same reproduces with mainline arch linux kernel without patches.

I don't have lockup on suspend but I do get a segfault of the ipu6-psys module on suspend/resume and have on every kernel that I've tried. I'm currently on 6.3.7 and the only way to restore operation is to reboot the system. Here is the kernel log+stack trace from the suspend request, it fails with "Modprobe Tainted":

@HuidaeCho I can confirm that they're likely related. I can re-create the suspend segfault behavior by unloading the i2c_ljca module, after having unloaded the relevant IPU modules. To be clear, the segfault does not occur and everything runs as expected if I remove the i2c_ljca lines. I run the following script to unload/reload the modules:

echo rmmod

sudo systemctl stop v4l2-relayd.service

sudo rmmod -f v4l2loopback
sudo rmmod -f intel_ipu6
sudo rmmod -f intel_ipu6_isys
sudo rmmod -f intel_ipu6_psys
sudo rmmod -f ov2740
sudo rmmod -f mei_vsc
sudo rmmod -f i2c_ljca

sleep 5

sudo modprobe i2c_ljca
sudo modprobe mei_vsc
sudo modprobe v4l2loopback video_nr=1 card_label='Camera' exclusive_caps=1 max_buffers=2
sudo modprobe ov2740
sudo modprobe intel_ipu6
sudo modprobe intel_ipu6_psys enable_suspend_resume=1 async_fw_init=1
sudo modprobe -f -v intel_ipu6_isys

Then in the dmesg log I have:
