Apparently, the current timeout is not always enough in case of task hungs on a loaded VM: https://groups.google.com/g/syzkaller-bugs/c/rI2gfkV02Ks We only wait in case of crashes, so increasing the value should have a significant performance impact.

Do you think increasing wait will help? It printed no output for more than 5 seconds, and the output stops precisely at the start of the first stack, it did not print any at all. For me it suggests that more likely it deadlocked. |

Hmm, yes, sounds reasonable. |
