我遇到的问题有点类似于此处描述的问题：鼠标和键盘冻结 Ubuntu 20.04
我的机器：
Thinkpad T14
Processor: AMD Ryzen 7 PRO 4750U with Radeon Graphics
Ubuntu 20.10
Kernel: 5.9.3-050903-generic
Bios:
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.2.0 present.
我的外接键盘每天都会卡死几次，每次卡住几秒钟。我尝试按照上述问题中的提示来调试问题，并在日志中看到dmesg键盘实际上断开连接并重新连接，有时会连续发生几次：

当这种情况发生时，我没有注意到任何规律——有时是在键盘几分钟不活动之后，有时是在写句子的过程中。
有什么办法可以解决这个问题吗？谢谢。
