Comment 3 for bug 1048258

The Cypress driver appears to make psmouse emit flurries of these pairs of "lost sync" / "driver resynced" messages -- usually between 20 and 100 pairs in each batch. On my Ubuntu 12.04 Sputnik XPS 13, the flurries sometimes occur when I rapidly tap and click on the pad randomly (I don't need to suspend/resume).

Aside from their appearance in dmesg they don't seem to cause any functional problem with the touchpad. In particular, I do not see the messages repeating in an "infinite loop" -- just occasional flurries.

@Serge, does your condition match what I describe above (occasional flurries)? Or are you actually getting new instances of these messages being added *continuously* to dmesg? Pound on your touchpad randomly for a moment to make a flurry of the messages occur, then run dmesg. Assuming that the last message printed is a "driver resynced", note its timestamp, then without touching the pad at all run dmesg a couple more times -- does the timestamp change or stay the same?
