https://bugzilla.kernel.org/show_bug.cgi?id=219748 --- Comment #6 from Mika Westerberg (mika.westerberg@xxxxxxxxxxxxxxx) --- Created attachment 307579 --> https://bugzilla.kernel.org/attachment.cgi?id=307579&action=edit Try to shorten SB access timeout Thanks for the logs! From the trace it looks like similar what already was seen with Pluggable hub connected to Intel hardware. The sideband accesses take some time and the hub interprets this as "issue" and triggers disconnect (or this is what it looks like). The attached patch shortens the timeouts to half. Can you try with it and see if that makes any difference? -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
