Well, having NVNODE be the default didn't change all that
much. Running update(8) had more of an obvious effect on
uptime during a "make build".
Adjusting the multiplier to 2 in the line referenced above
has allowed me to do a complete "make build" and other
activities without crashing.
Interestingly, my laptop runs a kernel that is largely the
same as the desktop that has been having trouble; the
difference is that the former has a pciide I/O subsystem,
while the latter has a pretty speedy SCSI one (PCI ahc
plus "options AHC_TAGENABLE" plus a fast disk).
