I've installed 6.0-CURRENT (sources of 12 May 2005) on free slice:
booted my 5.4-STABLE and followed instructions in src/UPDATING for 6.x:
To cross-install current onto a separate partition
--------------------------------------------------
# In this approach we use a separate partition to hold
# current's root, 'usr', and 'var' directories. A partition
# holding "/", "/usr" and "/var" should be about 2GB in
# size.
I made one 2G partition occupying whole slice newfs'd as UFS1.
<make sure you have good level 0 dumps>
<boot into -stable>
make buildworld
make buildkernel KERNCONF=YOUR_KERNEL_HERE
<maybe newfs current's root partition>
<mount current's root partition on directory ${CURRENT_ROOT}>
make installworld DESTDIR=${CURRENT_ROOT}
cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
make distribution failed, I ignored that.
make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd
<edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
<reboot into current>
<do a "native" rebuild/install as described in the previous section>
It boots, but later make buildworld always hangs machine silently
using 6.0 GENERIC kernel with ACPI. No reaction on Ctrl-T, no console
switching (cursor hides after the first attempt to switch vty),
but KDB is alive. I failed to disable ACPI using acpi_load=NO
so just renamed /boot/kernel/acpi.ko and booted without ACPI.
Then buildworld and other stages of '"native" rebuild/install'
complete successfully.
<maybe install compatibility libraries from src/lib/compat>
Skipped that.
<reboot>
Now 6.0 boots to multiuser mode with ACPI fully enabled or fully disabled.
make buildworld cannot be completed with ACPI - still silent hang
of userland and no console switching (keyboard leds do switch and
KDB works).
6.0's GENERIC does not boot to single user with debug.acpi.disabled="pci_link",
fatal trap 12 occures: page fault while in kernel mode,
fault virtual address 0x0, supervisor read, page not present
in acpi_pci_link_lookup+0x26.
Kernel and world were build with missing /etc/make.conf.
No ATA timeouts observed in any stage during my "exercises" with 6.0
