In a way I'm not surprised as nobody else has reported anything similar. I guess it's something really specific on my box, so weird. > BTW, could you please share your /proc/cmdline? This is the simplified command line with which I can reproduce the bug: $ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-6.9.0 root=UUID=61a268dc-df96-4e69-9272-928240dcc445 ro net.ifnames=0 > Also, was there any workload running with the suspend test? There is no special workload when I reproduce the bug. This NUC box is one of our test setups which I use to test ath11k and ath12k wireless drivers, but when I'm debugging this suspend issue none of the wireless drivers are not even loaded. I don't normally have a display connected to the box but I do run netconsole, although I just verified that I see the bug if I remove netconsole configuration from cmdline. The distro is Ubuntu 20.04.6 LTS. Oh, but I do have installed a WCN6855 PCI module to the box so that I can test ath11k. That can of course make a difference. And maybe also BIOS settings? I think is easiest if I try get more info about with my box first, it might be quite challenging for you to reproduce it. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
