Howdy. I've got myself an interesting situation. It seems as though amd64 is unable to collect crash dumps via savecore(8). Has anyone else seen this? From dmesg(1): Checking for core dump on /dev/da0s1b ... savecore: first and last dump headers disagree on /dev/da0s1b Feb 21 12:45:59 host savecore: first and last dump headers disagree on /dev/da0s1b savecore: unsaved dumps found but not saved ??? sys/amd64/amd64/dump_machdep.c and sys/i386/i386/dump_machdep.c are essentially identical. I'm not familiar enough with these innards, but reviewing savecore(8) didn't point out anything obvious. I'm dumping onto a twa(4) controller. Are there any known workarounds to get this info? I'm tempted to turn off swap in fstab(5) that way the next time the machine comes up after a crash, it'll still have the dump in tact and could poke at it as time permitted. Other suggestions? -sc -- Sean Chittenden
