Configuration: 2.2.5-STABLE client mounts /usr/obj and /usr/src off a 2.2.5-STABLE server. On the server, these directories are on /exports, and are loopback-mounted to /usr/obj and /usr/src via NULLFS so that make won't get confused about the pathname differences. The client's make world works great. The problem comes when I go to the server, and try to make installworld based on the client's build. During the first line of the make, the server panics: cd /usr/src && PATH=/usr/obj/usr/src/tmp/sbin:/usr/obj/usr/src/tmp/usr/sbin:/usr/obj/usr/sr c/tmp/bin:/usr/obj/usr/src/tmp/usr/bin BISON_SIMPLE=/usr/obj/usr/src/tmp/usr/share/misc/bison.simple COMPILER_PATH=/usr/obj/usr/src/tmp/usr/libexec:/usr/obj/usr/src/tmp/usr/bin GCC_EXEC_PREFIX=/usr/obj/usr/src/tmp/usr/lib/ LD_LIBRARY_PATH=/usr/obj/usr/src/tmp/usr/lib LIBRARY_PATH=/usr/obj/usr/src/tmp/usr/lib:/usr/obj/usr/src/tmp/usr/lib CC='cc -nostdinc' /usr/obj/usr/src/tmp/usr/bin/make reinstall Fatal trap 18: integer divide fault while in kernel mode instruction pointer = 0x8:0xf01b00b8 stack pointer = 0x10:0xefbffdfc frame pointer = 0x10:0xefbffe48 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 196 (make) interrupt mask = panic: integer divide fault (IIRC, it isn't always this panic, but it always panics instantly...) The loopback filesystems seem to work fine for all other purposes, so I'm at a loss to explain why the server fails. The only thing I can see is that it points all the FYI, there are a couple reasons why I am not building this on the server. The first is that I am forcing myself to treat that box like a NetApp or somesuch -- it's just a big disk on the net which I'm not allowed to play around with. The other is that for some reason if I do too much on that box, it will also panic. I think that the particular -STABLE I put on there originally isn't particularly stable :-) but as long as the box is left alone, it runs just great as an NFS server. We've verified the RAM and are quite sure it isn't a hardware fault. This panic is always something like: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor read, page not present instruction pointer = 0x8:0x0 stack pointer = 0x10:0xefbffb48 frame pointer = 0x10:0xefbffb84 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 1304 (install) interrupt mask = panic: page fault As a side note, is there a way to get this to work with symlinks instead of NULLFS? Attached is my kernel config. The only "odd" thing is that I'm running the latest dpt drivers for 2.2.5-STABLE (version 1.2.4). This box was installed using January 22's 2.2.5-STABLE snap, and has never successfully been updated, due to the above problems. Evan
