 Thanks, that was what I wanted to know.

 I will commit that patch then... at least, once we make sure it isn't
 causing the panics you're seeing.

 Dumps are usually not all that necessary - if you compile the kernel
 with ddb and set the ddb.onpanic sysctl to 1, it'll drop into the
 kernel debugger after a panic, at which point what you want to do is
 get a stack trace (type 'bt') ...also be sure to note the panic
 message itself.

 Not sure where that printout comes from...
