I'm using gcc 2.95.4 (on debian). The kernel I'm currently using is 2.4.19, with the kdb patch and apic_routing patches applied. Neither of these is required to reproduce the problem, they're just to help debug the problem.
that reminds me. when I originally tried to use the nmi watchdog to break into the debugger when the hang occured, I got the following at bootup:
Sep 3 14:56:49 localhost kernel: activating NMI Watchdog ... done.
Sep 3 14:56:49 localhost kernel: testing NMI watchdog ... CPU#0: NMI appears to be stuck!

I don't have things caught in the debugger currently, but I did check the registers at the time. bit 9 of eflags was enabled on both cpus.
