Not me....

Mine too. I have it stuck at various points, as can be shown by many
ppc_md.progress() calls ;-). Most of the time, it stops somewhere in
init/main.c, in the early stages of start_kernel():

asmlinkage void __init start_kernel(void)
{
[...]
        lock_kernel();
        printk(linux_banner);
        setup_arch(&command_line);
        printk("Kernel command line: %s\n", saved_command_line);
        parse_options(command_line);
[sometimes never comes here.]
        trap_init();
        init_IRQ();
[it can happen in init_IRQ() as well]
        sched_init();
        time_init();
[somewhere in time_init(), I've also seen it crash]
        softirq_init();
[if it got here, it succeeded for me]
[...]

I've tried to trace via ppc_md.progress() calls where it hangs, but
that's quite useles, as it doesn't always hang at the same place.

For the record, I've seen similar hangs with 2.3.99/2.4.0 kernels
before, when I had to reboot a few times before it would succeed. Also,
I'm using quik to boot my 7600/upgraded-G3; I've not had the time to
verify how it's behaving under BootX.

Comments? Solutions?
