Well... cam_calc_geometry seems to get called quite a bit. Almost everytime you touch the disk, in fact. fsck'ing a partition calls it, for instance. Console access is personally expensive (much driving, for instance), but from memory the debugging I put in cam_calc_geometry() would print before the correct output from dadone(). Your description reminds me of this --- but it's no less vexing that the output from dadone() has the correct sector and volume size and the ccg in cam_calc_geometry() has bogus data. I don't know if it's significant, but the correct numbers were: 279353684 sectors of 512 bytes The ccg structure comes up with: 3737169375 sectors of 3737169374 bytes Not entirely sensible. Interesting that they're close values. However, with different things on the stack, the values changed. Matt> Have you built & run a kernel compiled with "options CAMDEBUG" ? Matt> This may provide more insight into where things are going wrong. I put CAMDEBUG in the kernel, but it didn't seem to change the output that much. It seemed to dump the control block showing when geom tried to access the high block number --- and failed, but nothing else particularly useful.
