OK, I ran it with high system load (which as discussed earlier made the bug pop up more readily) for a little over 12 hours, and no freeze. In case logs are interesting, they are temporarily (~48h) here: dmesg log with handle_tx_event, but with "spurious event" messages filtered out otherwise the file is 400 times the size: https://tmpfiles.org/wvw5Fxo00DQt/dmesg-6.18.42-patch-2026-08-04-no-spurious.txt Filtered debugfs trace as directed by Michal earlier in the process: https://tmpfiles.org/w2wTFcoQ02zV/trace-6.18.42-patch-2026-08-04.txt Thanks for all your work.
