Very often the touchpad freezes without dmesg message.
But each time it freezes the CPU does to 100% for the process irq/125-ELAN260.
The bug frequency is then every minutes, some seconds, or longer.
Suspending and resuming the laptop increases the probability of the bug.
After a fresh restart, the bug does not occurs immediately. Maybe after one hour.

Very long freeze triggers messages in dmesg:
