3.18 regression: Error while assigning device slot ID, USB3 devices not detected

3.18 regression: Error while assigning device slot ID, USB3 devices not detected

[Robert Hancock]

I've got an Intel Haswell-based system with a Gigabyte Z87X-D3H 
motherboard under Fedora 21. After updating to the 3.18.2-200 Fedora 
kernel, I noticed some errors in dmesg and at least some of my USB3 
ports don't recognize any USB3 devices plugged into them:

[    0.560838] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[    0.560912] xhci_hcd 0000:00:14.0: Max number of devices this xHCI 
host supports is 32.
[    0.560990] usb usb2-port2: couldn't allocate usb_device
[    0.561098] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[    0.561163] xhci_hcd 0000:00:14.0: Max number of devices this xHCI 
host supports is 32.
[    0.561239] usb usb2-port5: couldn't allocate usb_device
[    0.561344] xhci_hcd 0000:00:14.0: Error while assigning device slot ID
[    0.561409] xhci_hcd 0000:00:14.0: Max number of devices this xHCI 
host supports is 32.
[    0.561484] usb usb2-port6: couldn't allocate usb_device

This worked fine under 3.17. Is this a known problem?

Yes it is, should be fixed in Linus's tree now and will be backported to
the latest 3.18-stable tree in a week or so.

Do you happen to know the commit id?

Tell me if this fixed the issue.
I got this gut feeling this might be something else.
It should have failed in 3.17 as well

OK.  We're tracking this in the bug Robert filed here:

https://bugzilla.redhat.com/show_bug.cgi?id=1183289

The patch should be in the next Fedora kernel build, so hopefully we
can get back to you soon.

The patched build seems to fix the problem with the ports not
recognizing SuperSpeed devices. I do get these errors in dmesg now
though, which also weren't in 3.17:
