Typically the issue arises every 1-5 days, though sometimes the issue does not arise for a week plus.=20 Of note: These computers are constantly communicating via serial communicat= ion (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 comput= ers have ran). This is on Arch Linux. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
