an8 016版本这个问题仍然存在，不过目前来看，貌似只有这台N49机器有问题(目前测试是使用sdb磁盘，更换为sdi磁盘也会触发crash，跟磁盘关系应该不大)；另外更换为另一台F51的机器，多次跑generic/650用例均未触发crash，麻烦看下是否需要关注。 # crash /usr/lib/debug/usr/lib/modules/5.10.134-16_rc1.an8.x86_64/vmlinux /var/crash/127.0.0.1-2023-10-17-14\:03\:57/vmcore crash 8.0.1-2.0.2.an8 Copyright (C) 2002-2022 Red Hat, Inc.
