SuperStrangeDome

Hi,

I found some spare time to continue hacking Madze's superdome. With some really strange hacks (see below) I'm now able to see a successful mount of a root filesystem over NFS, but no sign of userspace yet.

The strange hacks have to do with output to console and timing. Here is a list of things I've added to get both partitions up to the point mounting NFS root:

1. add 50 dummy prinkts after print_parisc_devices()
2. do a while (pdc_iodc_getc() != 'a') in iosapic.c after dumping Interrupt Routing Table (only needed if DEBUG_IOSAPIC_IRT is enabled)
3. do a while (pdc_iodc_getc() != 'b') in lba_hw_init before touching anything
4. carefull press a and b during boot. I need to press b for every found Elroy. If I'm too fast the partition locks up

Does this ring any bells ? Looks like a very timing sensitive thing, but what could be the cause of it ?

Crap can work. Given enough thrust pigs will fly, but it's not necessary a
good idea.                                                [ RFC1925, 2.3 ]
