tvmosaic_server slows down system

Post by jms » Sat Jul 25, 2020 2:06 pm

After starting the tvmosaic_server on my ubuntu system, the system became where inresponsive and videos where stuttering. This continued even after I stopped the server! After searching 2 days for the reason, I found many of these lines in the system journal:
> kernel: hpet: Lost 7161 RTC interrupts
This is a message from the high precision event timer. So the tvmosaic_server was programming millions of RTC interrupts. I guess this is a bug.
So I disabled the hpet: in /etc/default/grub I put "hpet=disable" as a boot parameter and ran "sudo update-grub" and rebooted.
Now the system is running smoothly.
