@sdc-g I have found a way to reproduce. Here it is: 1. With latest master code, change `apps/examples/hello/hello_main.c`, replace it with the progrom in your PR summary 2. change `esp32s3-devkit:tickless` config, enable `CONFIG_EXAMPLES_HELLO` 3. change `arch/xtensa/src/esp32s3/esp32s3_tickless.c` to make `esp32s3_setup_irq` request level2 interrupt. There is a patch [here](https://github.com/apache/nuttx/pull/14672#issuecomment-2558786070) 4. change `arch/xtensa/src/common/xtensa_vectors.S`, comment out the `break 1, 4` in `_double_exception_vector` That's all. With these changes, the system will have a level2 interrupt, and new thread is created frequently. Now build `esp32s3-devkit:tickless` config and flash the board. Run hello will trigger this error: ```` ******** Test Start ******** xtensa_panic: Unhandled Exception 2 task: hello dump_assert_info: Current Version: NuttX 12.8.0 b1bab5c7837-dirty Mar 18 2025 17:01:37 xtensa dump_assert_info: Assertion failed panic: at file: :0 task: hello process: hello 0x42022d5c up_dump_register: PC: 4202b27c PS: 00050030 ```` The PC here is `pthread_start`, this is what I said ***If window rotation related instruction is executed, error will arise*** Revert your this PR, then everything is OK. ```` nsh> hello Start TimeSliceThread ******** Test Start ******** Test Thread Test Thread Test Thread Test Thread Test Thread ```` You can revert and apply your this PR back and forth to see the effect, until you are convinced your this PR is harmful. -- This is an automated message from the Apache Git Service.
