Description

sanity test 244 hangs in recent testing. The last thing seen in the test_log is a hang during test 10 or 11

In all cases, the stack_dump is empty and the only thing seen in the console logs and dmesg is the test starting, rebooting and start testing sanity-sec. There’s about a one hour gap between when the test last reports in and when the node is rebooted
