Hello Pavel,
I will attempt to bisect the issue.
So far I can confirm it occurs in 5.15-rc1.
I also forgot to mention that this issue occurs on an arm64 platform
if it matters. Would you be able to test this issue out in an arm64
VM?
Hi, Zameer!
I think, I can build aarch64 kernel and test it in vm.
Btw, did you try to enable debug logs? debug=9 module argument will turn
on all debug logs and maybe there will be some additional information
about what actually happened
Test results from aarch64 vm. My qemu configuration is
```
qemu-system-aarch64 \
-machine virt \
-drive file=./debian-rootfs-aarch64.img,format=raw \
-cpu cortex-a57 -machine type=virt \
-nographic \
-smp 2 -m 4096 \
-kernel arch/arm64/boot/Image \
-net user,hostfwd=tcp:127.0.0.1:55555-:22 \
-net nic,model=virtio \
-device usb-ehci \
-usb -device
usb-host,hostbus=$BUS,hostaddr=$DEVICE,guest-reset=false,id=tp \
-append "root=/dev/vda1 rw nosplash"
```
if something is wrong here, please, let me know, i will retest. I am not
an expert in arm :)
And test results:

I didn't try to connect to my wifi, since your problem occurs even
before connecting
Any ideas about how to reproduce or what have I done wrong? :)
With regards,
