Description Tom de Vries 2017-08-05 09:52:13 UTC 
A test-case fails with launch timeout:
...
PASS: gcc.c-torture/execute/pr78675.c   -O1  (test for excess errors)
spawn nvptx-none-run ./pr78675.exe
nvptx-run: error getting kernel result: the launch timed out and was terminated (CUDA_ERROR_LAUNCH_TIMEOUT, 702)
FAIL: gcc.c-torture/execute/pr78675.c   -O1  execution test
...
Comment 1 Tom de Vries 2022-03-29 08:12:15 UTC 
The error message looks like the one produced due to the 5 second watchdog that is installed when the board is running a display manager.

Anyway, in order to run into this timeout, the test-case should hang, and it currently doesn't.  At least not on any of the boards I've recently tested with, with the supported drivers.  So, possibly this was fixed in gcc, or in a driver.

There's not enough information in here to reproduce, so closing as resolved-worksforme.
