commit 2926952b35d648eb1bca921662f0e64ab3fed29f Author: Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx> AuthorDate: Tue Oct 31 03:16:53 2023 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Tue Oct 31 11:06:16 2023 +0000 automation: fix race condition in adl-suspend test If system suspends too quickly, the message for the test controller to wake up the system may be not sent to the console before suspending. This will cause the test to timeout. Fix this by calling sync on the console and waiting a bit after printing the message. The test controller then resumes the system 30s after the message, so as long as the delay + suspending takes less time it is okay.
