[Kernel-packages] [Bug 2013390] Re: CPU Lockup related to xhci/DMA
I found a patch applied in Linux kernel 5.15.0-91.101 that fixes this bug -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/2013390 Title: CPU Lockup related to xhci/DMA Status in linux-signed-hwe-5.13 package in Ubuntu: Confirmed Status in linux-signed-hwe-5.15 package in Ubuntu: Confirmed Status in linux-signed-hwe-5.19 package in Ubuntu: Confirmed Status in linux-signed-lowlatency package in Ubuntu: Confirmed Status in linux-signed-lowlatency-hwe-5.15 package in Ubuntu: Confirmed Bug description: CPU lockup problems have been encountered on a number of computers running kernel 5.15 or later, but this problem could've been introduced in an earlier version. Three of these systems are running a light weight version of Ubuntu. The kernels that have been tested are 4.19, 5.15, 5.18, 5.19, 6.0, and 6.1. The basic setup that's running and causing problems is a program that starts several (4+) distinct processes and communicates with different ACM/USB concurrently. This problem can be encountered a few minutes after starting this program up to about a week later, but it generally happens after ~1-3 days. When the lock up occurs, if there are the same number or fewer CPU cores than the running number of running processes doing ACM/USB device communication, nothing else will execute due to all of the CPU cores being locked up until the watchdog frees things up. The longest lockup that has been encountered was over 20 minutes! The computers that this problem has been tested and verified to be present on are the NUC7i5BNK, the ASRock NUC BOX-1260P, and the LattePanda Delta 3. Although, this problem appears to be system agnostic; if kernel version ~5.15 or later is being used, it'll likely happen if this program is setup and run on any system when enough known ACM/USB devices are connected to it and communicated with concurrently from different processes. The main reason "this program" is being stated in a broad sense is because multiple different setups fitting that description have been tested trying to get around encountered problems in various clever ways and this problem has persisted regardless of what's been done.

Three of these systems are running a light weight version of Ubuntu. The kernels that have been tested are 4.19, 5.15, 5.18, 5.19, 6.0, and 6.1. The basic setup that's running and causing problems is a program that starts several (4+) distinct processes and communicates with different ACM/USB concurrently. This problem can be encountered a few minutes after starting this program up to about a week later, but it generally happens after ~1-3 days. When the lock up occurs, if there are the same number or fewer CPU cores than the running number of running processes doing ACM/USB device communication, nothing else will execute due to all of the CPU cores being locked up until the watchdog frees things up. The longest lockup that has been encountered was over 20 minutes! The computers that this problem has been tested and verified to be present on are the NUC7i5BNK, the ASRock NUC BOX-1260P, and the LattePanda Delta 3.
