https://bugzilla.suse.com/show_bug.cgi?id=1218455 Bug ID: 1218455 Summary: kernel: NOHZ tick-stop error: local softirq work is pending Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: opensuse@mike.franken.de QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Starting with kernel 6.6.6 (and continuing with 6.6.7) I get kernel: NOHZ tick-stop error: local softirq work is pending, handler #08!!! a few times within one or two minutes and during this time performance is degraded heavily. This happens about every two days, so it is not that much of a problem, but a bit annoying. system is: Operating System: openSUSE Tumbleweed 20231226 KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.113.0 Qt Version: 5.15.11 Kernel Version: 6.6.7-1-default (64-bit) Graphics Platform: X11 Processors: 8 × 11th Gen Intel® Core™ i7-1165G7 @ 2.80GHz Memory: 15,0 GiB of RAM Graphics Processor: Mesa Intel® Xe Graphics Manufacturer: Dell Inc.

This means that CPU is going idle with a NET_RX_SOFTIRQ softirq pending. This is not supposed to happen in an online CPU because at this stage if a softirq is pending, ksoftirqd should be pending, thus need_resched() should be set, and the tick shouldn't be stoppeable. One possibility though is that the CPU is going offline after the smpboot kthreads (including ksoftirqd) haven been parked (past CPUHP_AP_SMPBOOT_THREADS). In that case need_resched() may not be set even if softirqs are pending. But isn't networking supposed to deal with that somewhow? -- You are receiving this mail because: You are on the CC list for the bug.
