Hi all,
I'm dealing with some very weird behavior and have run out of ideas what else I could try to fix this.
My laptop takes about a minute longer than usual to boot when starting it via wake on lan instead of pressing the power button. During that time, the screen shows
Loading Linux linux-lts ...
Loading initial ramdisk ...which usually only appears for a few seconds, but whenever I use WOL it is stuck at this stage for more than 60 seconds during the subsequent boot process.
I tried comparing the output of dmesg after booting both ways to find out what the issue might be, but the only thing I've been able to determine is that the process seems to be happening in a slightly different order (and that the wol log is marginally longer). I did find this time gap in the wol log, which might correspond to the extra 60 seconds of boot time:
[ 4.358161] tsc: Refined TSC clocksource calibration: 2207.999 MHz
[ 4.358177] clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x1fd3b75da7f, max_idle_ns: 440795296082 ns
[ 4.358242] clocksource: Switched to clocksource tsc
[ 68.561549] AMD-Vi: AMD IOMMUv2 functionality not available on this system - This is not a bug.
[ 68.561637] ACPI: bus type drm_connector registered
[ 68.563202] ahci 0000:00:17.0: version 3.0but I haven't been able to make sense of this information. When booting normally, no such delay is documented in the log.
I uploaded the full content of both files here: turn on via power button | turn on via WOL
It's also worth mentioning that my laptop has a Qualcomm Atheros Killer E2400 network card, so I had to apply a kernel patch to get WOL to work at all due to a bug.
I initially had the stable kernel installed, but switched to the longterm kernel because I was not able to get the patch to work with the former.
I've made sure that fast boot and secure boot are both turned off in the BIOS/UEFI and fixed some PCIe Bus errors by adding "pcie_aspm=off" as a kernel parameter. Unfortunately, none of that seems to have helped with my main issue.
