you're not getting clock IRQ, which is usually IRQ 0. you need to see how your interrupt hardware and/or clock is working to create interrupts.

Usually you have to correct your pirq and mptable (or ACPI tables, if available) (Check the APIC entries in your mptable, as a first try)
In my previous post, I mentioned a good way to proceed is booting from the commercial BIOS and running LB util/getpir to view the PIRQ table and compare it to the irq_table.c of the LinuxBIOS being booted.
To check the MP table, boot the COTS BIOS & Linux and run LinuxBIOS util/mptable which will generate an mptable.c file on stdout. Compare this code to the actual mptable.c code in the LinuxBIOS that caused the boot problem. (The code that util/mptable generates must be hand edited to work under LinuxBIOS v2, so some differences should exist.)
Please note that some people consider running either util/getpir or util/mptable to be a waste of time. (I agree; Maybe these utilities could be fixed so they would be more useful on LinuxBIOS v2.)
Hope this helps.
