I'd need to compile the whole Debian kernel which takes quite a while O:-) But other than that... and especially as I'm seeing these: 2024-11-01T15:41:22.428940+01:00 heisenberg kernel: tpm_tis NTC0702:00: Ignoring error -5 while suspending errors... ... I wondered whether that rings any bells on your side with respect to: https://bugzilla.kernel.org/show_bug.cgi?id=216998 I short, ever since I got my current laptop, suspend2ram was broken, that is per default I get: # cat /sys/power/mem_sleep [s2idle] deep and that "soft" suspend works (but there the CPU, keyboard, touchpad and stuff is still on, drawing power and even the fan continues running). If I overwrite it to deep, I can go into suspend (or at least the laptop actually does a real suspend2ram, but when I power on (here it the really requires the power button, no longer only keyboard or touchpad movement) the system immediately freezes and the screen doesn't even light up. Not a show stopper, but still quite annoying. Having looked around for similar reports for quite a while I indeed found people indicating that TPM might be the issue, but even with disabling TPM in the BIOS it still fails. So after all it might be just some broken Fujitsu firmware... but if you'd have any idea what I could further try I'd be happy to hear about it. Thanks, Chris. PS: Thanks as well for the quick fix :-)
