Kernel tests sometimes hang #119

Open jbush001 opened 6 years ago

jbush001 commented 6 years ago

When running against Verilator. For example, tests/kernel/hello normally completes in around ~45 seconds on my machine, but sometimes it sits for minutes and does nothing.

I can reproduce this around one out of 10 times with tests/kernel/crash using the emulator.

However, I can't reproduce it after ~40 times using the emulator directly (without runtest). Perhaps there is a deadlock in the test harness.
