Thank you for the reply. It may be similar problem but I'm not getting "NULL pointer dereference error" as described in linked issue. I already created separate bug report at: https://bugzilla.kernel.org/show_bug.cgi?id=3D202513 I think this issue may be caused by firmware update for intel 8000 series which could be buggy itself or just uncovered bugs in iwlwifi driver: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git= /commit/?id=3D8707ef3313ee0f6737683c93aa2cb1dff6483643 Downgrading linux-firmware package to version before that commit seems to make this issue go away.
