Here's what I found: - The drivers/gecko/lasi.c changes made between 1999/10/19 and 1999/10/25 made the console unbearably slow. At first glance I suspect we're not handling interrupts properly, but I haven't looked at it in any sort of detail. I'll get to it soon, unless someone else does first. - I reverted someone else's one-line change to drivers/char/serial.c that was causing the console to barf when sash tried to display something. This was ultimately the only hard problem to track down. - We need ``argv_init[1] = NULL;'' in init/main.c, at least for the moment, so that we don't get sash's usage screen. - There are problems with the IODC console. If I set console=tty and boot with IODC, I get: Attempting to execute '/sbin/init' It's for the PA-RISC! It's executable! It has an appropriate version! The checksum checks out! Well, it *smells* like a valid SOM executable (start_brk) 40017000 (end_code) 0003c000 (start_code) 00001000 (end_data) 40008000 (start_stack) 20000028 (brk) 40017000 Kernel panic: Attempted to kill the idle task! In swapper task - not syncing I've not even begun to debug this. If you want to just get to a prompt, turn off the IODC console and set ``console=ttyS0'' in arch/parisc/boot/boot_code/ipl_c.c Aside from that, using the ramdisk that Chris made (on puffin.external.hp.com), you should be able to boot to a sash prompt, at least on the A180. I've not tried it on any other machine; I'll probably try it first thing tomorrow. Good luck-- -Phil
