mouse driver crashed on 4.15 kernel

[Yury Norov]

Hi Dmitry,

It just happened to me on standard Ubuntu laptop (Lenovo X1 gen 5), so
I had to reboot my machine. According to logs, there was also a problem
with the wifi, but wifi driver managed to recover the hardware.

Looking at dmesg I cannot find something useful because it was wiped
with a number of identical warning messages from the mouse and SMBus
drivers. 

I'm just a victim, and don't know much, but at least I can recommend to
use dev_warn_once() to avoid spamming the system log if things like this
happen. 

Some system information is below, and system log is attached. Hope it
will help.

Thanks,
Yury
