----------------
I switch X11's synaptics to kernel's synapticstouchpad driver(http://wiki.freebsd.org/SynapticsTouchpad).
sysctl:
hw.psm.synaptics_support="1" 
It works well.but yesterday I noticed the touchpad not work in X.when i logined in the console and tried to use touchpad,system panic.
system:lenovo T61

State-Changed-Why:  
To submitter: could you try to establish where in the kernel 
this crash is happening, with: 
addr2line -e /boot/kernel/kernel.symbols 0x8:0xffffffff804fc8ba 

Also, is there any chance you have a core file from this panic?  If 
your system is set up to save core files, it will be in /var/crash.

 Hi,
 
 I'm afraid I do not understand.  Are you saying that you no longer see
 the panic you reported?  I can't see how sendmail can be in any way
 related.
 
 If you do still get the panic, then even if you cannot get a core dump,
 please run the "addr2line" command as above with the number from the
 "instruction pointer" line from the panic.
 
 Thanks,
 
 Gavin

To submitter: I'm afraid I do not understand your last response.  Are you 
saying that you no longer see the panic you reported?  I can't see how 
sendmail can be in any way related. 

If you do still get the panic, then even if you cannot get a core dump, 
please run the "addr2line" command as above with the number from the 
"instruction pointer" line from the panic.
