Hi, all:
I have a problem about etho bringing up. The error output is following:
Bringing up interface eth0: dhcpcd[440]: timed out waiting for a valid DHCP server response Determining IP information for eth0... failed.
So I check the packets transmitted between DHCP server and client base on LinuxBIOS. I find the client can submit a request, but it can not receive the ACK from DHCP server, so it fail to determine its IP.
The output differences between the normal BIOS and LinuxBIOS:
normal BIOS: ENABLING IO-APIC IRQs Setting 8 in the phys_id_present_map ...changing IO-APIC physical APIC ID to 8 ... ok. Setting 9 in the phys_id_present_map ...changing IO-APIC physical APIC ID to 9 ... ok.

Does the problem come from mptable.c? How can I do next? Who can tell me? Thanks a lot!
