Hi all,

We have a IBM xSeries 336 which has 2 Pentium 4 (EM64T) 3.2G with 2GB memor=
y.
When we boot it with 6.0-RELEASE/amd64, it hangs after acd0 is shown.
However, if apic is disabled, then it boots. For 5.4-RELEASE/amd64, it work=
s
great. A 7.0-CURRENT (SNAP009, Nov/2005) shows the same behavior.

To have it boot, I set following in loader.conf

hint.atkbd.0.disabled=3D"0x4" # otherwise, I lose my keyboard
hint.apic.0.disabled=3D"1"

The verbose dmesg with/without apic, and the asl dump (with bios version 1.=
12,
the latest one found on IBM site) are available at:

http://www.rafan.org/FreeBSD/x336/

BTW, the SCSI timeout message from dmesg-noapic.txt is a bit wired. If I bo=
ot
without verbose message it does not show, everything works great. With
verbose booting,
those messages show up and it takes me a lot of time to get into multiuser =
mode.
