Subject: [bugzilla-daemon@kernel.org: [Bug 218360] New: Disk drive of TBT3/USB4 storage device can’t show up if connecting behind TBT3 dock or some USB4 docks DFP TBT port]
Date: Wed, 10 Jan 2024 13:00:21 -0600	[thread overview]
Message-ID: <20240110190021.GA2113949@bhelgaas> (raw)

#regzbot introduced: d3fcd7360338 ("PCI: Fix runtime PM race with PME polling")

Sanath, thank you very much for this report and the bisection!

I assume this happens on hot-adds, i.e., you boot the kernel, then
connect a USB4 dock, then connect the TBT3/USB4 storage device to the
dock?

Would you be able to attach the complete dmesgs log from working and
failing kernels?  The ideal would be from d3fcd7360338 ("PCI: Fix
runtime PM race with PME polling"), which fails, and 5cd903bce9dd
("PCI/VPD: Add runtime power management to sysfs interface"), which
presumably works.  But v6.7 and v6.5 is OK too.

Also the output of "sudo lspci -vv", which I assume doesn't depend on
which kernel you're running.

Bjorn

	or some USB4 docks DFP TBT port
Message-ID: <bug-218360-41252@https.bugzilla.kernel.org/>

https://bugzilla.kernel.org/show_bug.cgi?id=218360

            Bug ID: 218360
           Summary: Disk drive of TBT3/USB4 storage device can’t show up
                    if connecting behind TBT3 dock or some USB4 docks DFP
                    TBT port
          Reporter: Sanath.S@amd.com

The disk drive of the TBT3/USB4 storage device can’t show up behind TBT3 dock
and some USB4 docks have a DFP TBT port.

TBT3/USB4 storage device can be authorized, the disk drive doesn’t show up.

Issue reproduce sequence: Connect USB4 dock to host → Connect TBT3/USB4 storage
device to dock DFP TBT3 port → TBT3/USB4 storage device disk driver can’t show
up.

The issue was observed in the latest mainline kernel 6.7.


Failing on all the below combination

HP Thunderbolt Dock 120W G2 HSN-IX01    
HP Hook 2.0 USB4/TBT4 Dock (PV Phase)   
CalDigit TS3Plus+ Thunderbolt Station 3 Plus    
Dell Thunderbolt Dock – WD19TB
