I have a core dump here. -current from 15. January, ffs_softdep.c 1.52.
Got one crash during buildworld (but didn't have core dump enabled),
so last night I started a "make buildworld; rm -rf /usr/obj/whatever"
loop. Sure enough, it crashed again the third time through the loop:

I had written down the routine names from the first crash - this is
exactly the same crash as first time (but different from the one that
Alexander Leidinger is seeing). Other details:
- Abit BP6 motherboard, 2 x Celeron 366, no overclocking. IBM DPTA-372730
disk on UDMA-66 controller. Softupdates enabled on all file systems.
- Kernel config file and boot messages included below.
The core dump is right now being copied over a 64 kbps line, to a more
accessible location, should be available in a couple of hours. If anybody
would like a copy, please send me email.
