I have isolated the cause of this bug to this commit: https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/noble/commit/?h=Ubuntu-6.8.0-20.20&id=71eb6b6b0ba93b1467bccff57b5de746b09113d2
All versions that I tested before this commit during my bisect passed the aiol test at least 15 times in a row, and all versions after this commit panic during at least one test. To confirm, I reverted this patch on the latest 6.8 Ubuntu kernel (which was previously panicking reliably within 5 tests) and verified that, with that change, it passes the test at least 15x in a row without any panics. The contents of the patch also support this conclusion, as the patch is a change to the Linux AIO interface that introduces new calls to spin_lock_irqsave() and wake_up_process() inside aio_complete(), which corresponds with the content of the traces I have observed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2058557 Title: Kernel panic during checkbox stress_ng_test on Grace running noble 6.8 (arm64+largemem) kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2058557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
