2024-01-26 05:45:56 Po-Hsu Lin description Issue found with 5.15.0-94.104~20.04.1 generic-64k openstack ARM64 instance. This is not a new bug, it's just we are re-using bug 1949617 for zram01 timeout issue, but that one is for specific bare-metal instance. Thus I am opening this for the check_read_mem_used_to time out issue: TBROK: "check_read_mem_used_total /sys/block/zram5/mm_stat" timed out Test log: INFO: Test start time: Fri Jan 26 02:53:32 UTC
