Since I'm low on time to mess around and want to move on to crypto stuff... please assist if you have time. I'm writing an architecture manual and other projects at the moment so it would be nice to have this workstation/server back as other work depends on it. My laptop doing double duty is grinding to a halt/swapping excessively. I'd love to dabble with kernel internals but there comes a point when I have to consider what is just basic needs for a production machine vs. dev workstation. I did appreciate the chance to review GEOM sources and the GEOM tutorial but that's about all I've done so far. I assume debugging will take half a day unless someone knows exactly where to point me. - I got it to boot using bootloader from floppy but didn't ever manage to get it back to bootable state from ad0. I did change the mbr to be at offset 0 instead of 63 which drastically reduced the radical/loopy slice entries. It looks like the difference between offset of 0 and offset of 63 causing something wrong with the hashing/MD5 function avoiding duplicate specification. This wasn't occurring previously even though the disk layout on this machine may be dated/dumb on my part as admin. See: - http://afields.ca/bsd/messed-geom.ps (dot geom tree) - http://afields.ca/bsd/messed-geom.xml (sysctl -b kern.geom.confxml ) - http://afields.ca/bsd/afields-5.4-p6-dmesg.txt (dmesg) FreeBSD 5.4-RELEASE-p6 #0: Tue Aug 16 10:34:25 EDT 2005 .. WARNING: Expected rawoffset 0, found 63 WARNING: Expected rawoffset 0, found 63 ... Also with this kernel: USB crashes both on disconnect of flash device w/ volumes mounted (on umount/at shutdown) -- often I have a loose cable and when usb keyboard is removed/KVM cycled.
