Logs are available at http://server.roeck-us.net:8010/builders, in the 'next' column. Bisect points to 'x86/irq: Enhance __assign_irq_vector() to rollback in case of failure'. Bisect log is attached below. Reverting this patch as well as the subsequent patches in arch/x86/kernel/apic/vector.c fixes the problem.
