Hi. Upgraded my 5.4 box vith sources to 6.0 with sources from July 31'st 2005. Did a make buildworld, buildkernel, installkernel, mergemaster -p, installworld and mergemaster. When it boots it stops at: atapci0: rid 0x20 is memory, requested 4 atapci0: Reserved 0x20000 bytes for rid 0x20 type 3 at 0xf7040000 atapci0: Reserved 0x1000 bytes for rid 0x1c type 3 at 0f7065000 atapci0: [MPSAFE] ata2: <ATA channel0> on atapci0 ISO cd FreeBSD 6.0 beta1 boots fine. regards Claus
