Bug Description

[Summary]
During the kernel migration test, I found that a few HP laptops are unresponsive over SSH, after checking them physically, they still can move the mouse or launch terminal with hot-key, but failed to execute certain commands like sudo reboot.

The last part of checkbox log was recorded while running Wi-Fi related tests, then the test timed out. Their common point is using the same wifi module which is Qualcomm-17cb:1107.

[Reproduce steps]
1. Install GM image
2. Run dist-upgrade to upgrade to 6.14-oem kerenl
3. Run checkbox sru test plan

[Failure rate]
1/1
