8.2-STABLE GENERIC kernel will not build

[Bill Tillman]

I updated the sources on one of my FreeBSD-8.2-STABLE servers and
rebuilt the GENERIC kernel just last night. All went well. This morning I
updated the sources on another machine and rebuilt a custom kernel and
all went well.
 
This evening I updated the sources on a 3rd server and the make 
buildworld went well, but when I tried to build the GENERIC kernel on
this one I get:
 
/usr/src/sys/dev/usb/usb_process.c:104: error: too few argument to
function 'kthread_suspend_check'
*** Error code 1
 
Stop in /usr/src.
*** Error code 1
 
Stop in /usr/src.
 
I tried the build twice and both times it failed this way. Any suggestions?
