funny thing, I picked up a V210 the other day and it too has problems with whatever is currently in snaps. RAMDISK is fine, I can install the machine without issues but as soon as I boot into the installed GENERIC.MP kernel, it hangs within 5 seconds, usually during mountroot/fsck. 7.8-stable is fine. I was going to bisect diffs but never got to it due to the holidays. -ml > Rebooting with command: boot disk /bsd.snap -d > Boot device: /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/disk@0,0 File and > args: /bsd.snap -d > OpenBSD IEEE 1275 Bootblock 2.1 > ..>> OpenBSD BOOT 1.30 > Can't read disk label. > Can't open disk label package > Booting /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1/disk@0,0:a/bsd.snap > 10542576@0x1000000+528@0x1a0ddf0+154196@0x1c00000+4040108@0x1c25a54 > symbols @ 0xfe978400 544212+165+698760+491505 start=0x1000000 > [ using 1735680 bytes of bsd ELF symbol table ] > console is /ebus@1f,464000/serial@2,80 > Copyright (c) 1982, 1986, 1989, 1991, 1993 > The Regents of the University of California.
