我的联发科 MT7922 802.11ax 网卡在从 6.2.0-21 升级到 6.3.0-7 官方 ubuntu 内核版本后断开连接。选择旧内核后，一切正常，但选择 6.3.0-7 后，我的plymounth磁盘解密屏幕显示在左上角而不是中间，启动后我的无线网卡工作了一段时间，然后突然停止 5 秒，然后再次工作。
dmesg除了控制台中的 ping 统计信息外，或中不显示任何信息/var/log/syslog。
我的笔记本电脑是联想 Thinkpad L14

如您所见，没有显示有关断开连接的信息。
我尝试禁用省电功能iw dev wlp6s0 set power_save off，但没有帮助。
如果有必要的话，我可以对内核版本进行二分法分析以找到问题的根源，但这样做需要一点帮助。
此外，我还看到Reddit用户发现卡的一个版本中存在漫游问题，但我不确定如何使用来禁用漫游iw。
