Dear Linux folks,
Booting Linux on the Intel Tiger Lake Dell XPS 13 9310, there is a 260
ms delay during startup.
[ 0.298217] ACPI: Power Resource [D3C] (on)
[ 0.558918] ACPI: Power Resource [PIN] (off)
As it’s off, I assume, it’s some kind of timeout. I uploaded the logs
and the ACPI table dumps to the Linux bug tracker [1].
If you could suggest, how to debug this further, that’d be great.
I also suggest, that Linux prints a warning if certain parts take too
much time, so firmware developers or engineers are finding bugs in their
code early.
Kind regards,
Paul

This is still an issue with Linux 5.17.3. Is there an easy way to debug
this? The device is in production use by a user, so I cannot do a lot of
reboot cycles.
I also thought, Intel’s QA lab has access to several Dell systems, and
could maybe reproduce this.
It’d be great if you could comment in the Linux kernel bug tracker [1].
Kind regards,
Paul
