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.
