>Description:
The problem is connected with the notebook HP NX6125 and occurs only when kernel is booted with hw.psm.synaptics_support=1.

When the touchpad is not used for a few seconds, attempt to move the cursor fails because it is frozen, after few seconds (4-5) it starts working and keeps doing it but only when it is constantly used (with 1-2 seconds' breaks in using it). After some time with no move, the problem appears again.

When touchpad is not used in kernel prints "psm0: lost interrupt?" with 1-2 seconds interval.

When hw.psm.synaptics_support=0 (touchpad working as normal mouse) problem not occurs but kernel still prints "psm0: lost interrupt?".

>How-To-Repeat:
Set hw.psm.synaptics_support=1 in /boot/loader.conf, boot kernel and try using /dev/psm0 device e.g. in X (driver synaptics/mouse doesn't care - freezes occuring in both).

Subject: Re: kern/122046: [psm] Synaptics touchpad freezes (psm0: lost
	interrupt?)
Date: Mon, 24 Mar 2008 19:42:29 +0100

 I have set debug.psm.loglevel=4 in loader and boot kernel with
 hw.psm.synaptics_support set to 0 and 1.
 
 I think that "psm0: lost interrupt?" messages it's not a problem but
 this:
 psmintr: delay too long; resetting byte count
 psmintr: 00 00 90 8a 08 c0
 psmintr: out of sync (0000 != 0080) 210 cmds since last error.
 psmintr: discard a byte (1)
 psmintr: 00 90 8a 08 c0 57
 psmintr: out of sync (0000 != 0080) 0 cmds since last error.
 psmintr: discard a byte (2)
 
 
 dmesg parts (with hw.psm.synaptics_support=1):

 I have read Synaptics Interfacing Guide, atkbd/psm.c and debug outputs
 and I have three conclusions:
 - "psmintr: delay too long; resetting byte count" message always occurs
 after one/serie of "psm0: lost interrupt?" messages,
 - packet after psm delay (resetting bytes count) always have two first
 bytes zeroed e.g. 00 00 90 8a 08 c0 (byte with sync mask [0xc0] is
 last), I suppose that this bytes are coming from not-completly read last
 packet (last packets looks like "80 00 00 c0 00 00"),
 - 4-5s freezes = waiting after sync errors (2 sync errors =
 debug.psm.errsecs).
 
 I don't know why packet before "psm0: lost interrupt?" is not completly
 read.

 Dear Sir/Madam,
 
 I am reproducing this problem on an HP 8710p with 8.0-RELEASE.  The
 notebook has a Synaptic pad+stick combo.  I find it interesting that
 this hardware was working on 7.2 without any problems, but now in 8.0
 there is this pain: the mouse freezes up for a few seconds, particularly
 when switching between consoles and X.
 
 As per Artur's original description, I have increased the log level and
 confirm that I have exactly the same problem... with some interesting
 additions.  Seems that button 9 (right mouse button) on the touch pad
 also generates button 4 events.  This is happening at the moused layer
 and this then gets passed up (so things like xev report 4 and 9 Button
 Release events while the button is held down).
 
 Regards, Mike Grant.

 I'm experiencing the same issue on my Lenovo L420. The same symptoms are for
 using trackpoint and touchpad. On the other hand touchpad and trackpoint on
 Dell E6520 are working fine.

 =46rom my observation: this issue doesn't occur (at least not too often) when=
  kernel
 is compiled with WITNESS + INVARIANTS. Cursor movements is smooth and not e=
 rratic.
