--- Comment #42 from Mika Westerberg (mika.westerberg@linux.intel.com) ---
Okay you unplug the dock on purpose? Okay I see.
So what should happen is that these PCIe root ports do support active link
reporting so with recent kernel (v6.5 I think) the PCI core checks if the link
is active before it issues the ~60s (arbitrary) wait. However, it does not seem
to work in your case. Now, you have "mem_sleep_default=deep" which forces S3
and possibly enters into completely untested BIOS paths (these systems are
pretty much all s2idle).
Can you add CONFIG_PCI_DEBUG=y to your .config, and remove the above option
from the command line, and see if it reproduces? If it does can you attach the
full dmesg again?
