The boot sequence leading up to the panic was... .. Mounting all filesystems... Clearing /tmp. Creating a.out runtime link editor directory cache.

So I'm wondering now if this is a more or less intermittent issue and I just got lucky that first time I was successfully able to boot 4.0. Or it could be that this mutex issue is totally dependent on pmap.c being DEBUG. I think it's probably not an issue of my userland being 1.6.1 because the first time I hit the panic it was so early on boot, but that's just a hunch.Strange that this happens with your TT, but not with my Falcon. Are you able to boot with current kernel which has only SCSI fix ? If it still works, then it's probably DEBUG in pmap.c and/or some other possible changes that happened in NetBSD current source tree between SCSI fix kernel and pmap.c DEBUG kernel or I was lucky enough to boot DEBUG kernel two times with Falcon :)
It would be helpful if we had a guaranteed way to reproduce
the crash on David's system, ideally without needing the
filesystem mounted read/write (so there would be no risk
of corruption and no need for fsck to check the filesyste,
after reboot).
David, if you have time could you maybe look at building
benchmarks/forkbomb or sysutils/crashme on your system (I
imagine under 1.6 would be fine), then booting your system
withe the test kernel into single user mode (so the
filesystems are mounted readonly) and running them to see
if they crash?
Alternatively if its related to disk IO you could try
booting into single user and running 'fsck -fn' which runs
fsck on all disks but disables any writing back (its a
quick way to generate a lot of non sequential disk reads)
Anyone know a reasonably priced source of Falcon or TT030
hardware? :) Someone wants £395 for a Falcon on eBay
at the moment... :/
