Please open a bug on bugzilla.kernel.org and attach full output
of lspci -vv and dmesg. Be sure to add the following to the
command line:
pciehp.pciehp_debug=1 dyndbg="file pciehp* +p"
Once you've done that, please report the bugzilla link here
so that we can analyze the issue properly.
what's going on here.
Again, if you get such timeout messages, it's usually not caused
by a bug in the driver but by an erratum in the hardware,
i.e. the hardware neglected to signal Command Completed in response
to a Slot Control register write.
Thanks,
