Re: "vnlru_proc: vnode recycler stopped working!" when doing a make buildkernel

:I thought this was just a problem with the oct 16 copy I had, since I 
:knew that was when the VFS layer was in severe flux, but I've reproduced 
:it several times afterwards with an dec 5 copy as well.
:The following appears to semi-reliably trigger the abovementioned error 
:make buildworld/quickworld
:make buildkernel KERNCONF=DOOM
:make installkernel KERNCONF=DOOM
:make installworld
:It appears to most commonly happen during buildkernel, but I'm not 
:entirely sure.
:The message in the subject pops up regularly, everything related to disk 
:seems to grind to a halt, and I'm unable to shut down the box in a 
:normal fashion. This is on a playbox, so if  you're unable to reproduce 
:this, I'll be happy to assist in trying to find the bug, given good 
:enough instructions for how to proceed.

    Jan, see if you can get kernel core out of it.  You may have to
    set sysctl kern.sync_on_panic=0, but then ctl-alt-esc'ing into
    the debugger (when the machine is in this locked up state) and
    typing 'panic' <return> (probably <return> a second time) should
    do it if you have the dumpdev set.
