No worries, @samde, just hope it helps. --- Does this help us with a way to reproduce it for the Canonical kernel engineers? ---
I could not force the network hang using any stress tests for power management or the network. I had to wait, hence my long delays between updates. Incredibly frustrating for someone with my limited patience. --- 2026-04-09 Thursday kernel freeze: would a significant fault like this get patched in after 26.04 is released? Ideally this would not be released in this state, given the severity and the prevalence of the hardware. --- I'm not so sure that it is significant in the eyes of an engineer as the pi is considered a hobbyist device and I may have made it even less so now that a workaround is available. I will poke around but am not an experience kernel developer with full knowledge of the RP1 hardware timings nor the algorithms they are employing. At least we know what it is now, though, and that may help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2133877 Title: Complete network hang on Raspberry Pi 5 with kernel 6.17 under load - possibly related to CPU frequency scaling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2133877/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
