I have an Intel DP35DP board running 8.4 AMD64. I cannot boot (from DVD or USB mem stick) a 9.1 or later AMD64 kernel (I've tried 9.1, 10.1, and11.0-CURRENT-amd64-20141113-r274463). All kernels will boot to the line:
Timecounters tick every 1.000 msec
and then it hangs. I have upgraded the BIOS to the latest currently available on the Intel website. I have fiddled with many BIOS switches including turning off HPET. I have tried booting without ACPI via the loader prompt.
I have tried pulling all boards and devices except those absolutely needed: keyboard mouse (both USB) hard drive, DVD (both SATA) and video.
I have tried booting verbose and then got the following output after the above Timecounters line:
vlan: initialized, using hash tables with chaining
tcp_init: net.inet.tcp.tcphashsize auto tuned to 16384
lo0: bpf attached
hpt27xx: no controller detected.
hptrr: no controller detected.
hptnr: no controller detected.
I have a report from another person on the hackers list that they have this board working under 9.1, 9.2 and 9.3. He and I have the same BIOS revision and board as reported by dmidecode
I can make this system available to anyone in the SF bay area if that makes debugging easier.
