https://bugzilla.kernel.org/show_bug.cgi?id=216728 --- Comment #22 from Mika Westerberg (mika.westerberg@xxxxxxxxxxxxxxx) --- Created attachment 303594 --> https://bugzilla.kernel.org/attachment.cgi?id=303594&action=edit Use pci_dev_wait() to check if the xHCI is reponsive after the link is activated Can you try the attached patch? It seems that sometimes it takes longer than the additional 100ms (up to seconds) for the xHCI to become responsive after the PCIe link has been trained. This fixes the issue on the Dell Come Lake based system at least. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
