Occasional lockup/panic

[Jason SW <jason.hsw@xxxxxxx>]

Hello,

I've been having this problem for a while now. I'm using Speakup on a 
laptop running Arch Linux, and using a Bluetooth keyboard. Occasionally, 
when quickly reviewing the screen, especially by word, or if I go up a 
line and then try to read the next word quickly, the kernel will either 
panic or produce soft/hard lockups, and I have to force the machine to 
power off.

The last time this happened, I found the lockup messages in the Systemd 
journal.
I also added panic=30 to my boot parameters, and set 
kernel.hardlockup_panic to 1, so hopefully I won't have to power my 
laptop off again. Here are the messages I got.
