I've been running RELENG_5 -D2005/04/25UTC on a CF-based system
(PC Engines WRAP.1C v1.03; 640 KB Base Memory; 130048 KB Extended Memory)

after a few hours (mainly idle and ntpd), I was surprised to note
on the console:

db>
unfortunately, I won't be able to take a dump because the CF has
no swap.
Anyone have an idea what this could be, and what I could type into
db> to get further info?
One thing that I changed on this HW yesterday was to add a Mini-PCI
HiFn card:
hifn0 mem 0x80040000-0x80040fff,0x80000000-0x80000fff irq 12 at device 13.0 on pci0
hifn0: Hifn 7951, rev 0, 128KB sram
before that change, earlier RELENG_5 systems didn't demonstrate
any such an "idle" panic on said HW.
non-verbose dmesg and kernel config image are available, and I will
leave the db> there, awaiting suggestions.
