https://bugzilla.kernel.org/show_bug.cgi?id=214021 --- Comment #7 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) --- This means the problem is somewhere below xhci_alloc_dev. In other words, the problem is in the xhci-hcd driver, and it has no connection to the commit you found. Except perhaps that increasing the time delay manages to avoid the bug somehow. You can try enabling dynamic debugging for xhci-hcd. On the boot command line, add: dyndbg="module xhci_hcd =p" and see what shows up in the dmesg log. -- You may reply to this email to add a comment.
