I have Ali based Toshiba notebook. In dmesg I see frequent resets like:
input: AT Translated Set 2 keyboard as /class/input/input6
input: AT Translated Set 2 keyboard as /class/input/input7
input: AT Translated Set 2 keyboard as /class/input/input8
Interesting is I checked sysfs after having seen those messages and
{pts/0}% LC_ALL=C ll /sys/class/input
total 0
drwxr-xr-x 6 root root 0 Jan 21 13:14 input1/
drwxr-xr-x 4 root root 0 Jan 21 23:54 input8/
drwxr-xr-x 2 root root 0 Jan 21 13:14 mice/
lrwxrwxrwx 1 root root 0 Jan 22 00:02 mouse0
- -> ../../class/input/input1/mouse0/
lrwxrwxrwx 1 root root 0 Jan 22 00:02 ts0 -> ../../class/input/input1/ts0/
So it appears similar to SCSI - old instance is stuck and new instance is
created.
How can I debug it further? System information:

Hmm, I lost you... input1 is mouse, input8 is keyboard. I don't see
anything "stuck" here.

I would start with opening the notebook and reseating keyboard cable.
