https://bugzilla.kernel.org/show_bug.cgi?id=207283 Bug ID: 207283 Summary: Allen & Heath ZEDi-10 instability Product: Drivers Version: 2.5 Kernel Version: 5.6.3 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: ben@xxxxxxxxxx Regression: No Created attachment 288471 --> https://bugzilla.kernel.org/attachment.cgi?id=288471&action=edit Kernel config I keep seeing various errors in dmesg which I will show below, and occasional disconnects. I've tried it on two different computers and it's only happening on one of them so I don't think the hardware itself is at fault, but I'm sure people on the list here will know a lot more about it than I do. Sometimes I get the error "ERROR Transfer event TRB DMA ptr not part of current TD" as well, and occasionally "parse_audio_format_rates_v2v3(): unable to find clock source (clock -71)" but often it's just disconnecting the port, which then reconnects within a second or so. It's using the xhci_hcd driver, I've looked in to disabling xHCI in the BIOS after some searching on the web but this laptop doesn't have any option to do that, and it's also using that driver on the other laptop that doesn't seem to have this issue. I am attaching the current kernel config, as well as some dmesg extracts with 'module xhci_hcd =p' set in /sys/kernel/debug/dynamic_debug/control.
