Hmm. I've been trying to build the world on this (other) machine for days now, and have been plagued with no end of problems. I am _not_ convinced that the machine is 100% hardware reliable. Although earlier this year (march-april) it was worlding every couple of weeks OK, it has (I believe) had a memory swap since then. (P120, Soyo Triton, NCR & 2G seagate). Initially the build was failing _consistently_ when compiling libncurses/lib_options -> lib_options.so; the machine would spontaneously reboot. I've been supping as close as I could, watching for changes filtering through from JD; the kernel it's currently running's /sys/vm Id strings are at the bottom of this message. The reason I post this is just that it looks VM-ish and it _may_ be helpful. Also, the machine is still sitting in DDB if there are extra things I can do to shed light on the subject. The trap is (summarised) as follows : trap 12 fva 0x66 ip 0x8:0xf012f2c6 sp 0x10:0xefbfff28 fp 0x10:0xefbfff3c cs base 0x0, limit 0xfffff, type 0x1b dpl 0, pres 1, def32 1, gran 1 eflags interrupt, resume, iopl = 0 proc 4 (update) interrupt mask (none) _vfs_msync + 0x4e testb 0x1,0x3d(%eax) _sync + 0x40 _kproc_start + 0x32 _main + 0xcc If it makes a difference, the kernel was built on a -STABLE system using /usr/sbin/config from HEAD. Ideas?
