https://bugzilla.kernel.org/show_bug.cgi?id=217242 Bug ID: 217242 Summary: CPU hard lockup related to xhci/dma Product: Drivers Version: 2.5 Kernel Version: 6.1.14-1-lts Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: miller.hunterc@xxxxxxxxx Regression: No Created attachment 304018 --> https://bugzilla.kernel.org/attachment.cgi?id=304018&action=edit cpu hard lockup Utilizing Intel NUC11ATKC4 computers, there is an issue of CPU hard lockups that occurs seemingly randomly. Typically the issue arises every 1-5 days, though sometimes the issue does not arise for a week plus. Of note: These computers are constantly communicating via serial communication (request-reply pattern) to an embedded device via USB to UART cable. Unsure if that may contribute - will start test next week to see if issue still arises when serial communication does not occur. This issue has been seen as far back as linux-lts 5.15.62 (not saying that's when the issue started, just that is the earliest release that these computers have ran). This is on Arch Linux. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
