Kernel Regression Testing

     We will be performing kernel regression testing to try to determine what commit introduced the rcu expedited timeout bug in the 5.19 kernel to assist kernel developers in correcting the situation.  Because it can take several weeks for this to manifest on an unbusy workstation, I will be trialing various kernels on our web server and mail server which are busy enough that they generate errors in a short time.  This may result in brief (under 2 minute) interruptions in service on our mail and web services but are necessary to determine the cause and eliminate this issue on Linux kernels moving forward.
