I'd missed the bit about the PIIX3 in your original post. I had a similar experience with this controller, but in my case, it was a mass storage problem. Using a new compile of 2.4.19 (it was some time ago), and a Samsung-badged (identifying as PQI) USB flash card adapter, everything came up first time, hotplug worked properly, and I could read and write a card. However, on trying to copy multiple files from the card, things went smoothly up to about 12MB, then the kernel locked up with two flashing keyboard LEDs, and it was reboot time. I tried upgrading to 2.4.20 when that arrived, but all the same things happened, and, since 2.4.20 broke a few other things, and I'm lazy, I went back to 2.4.19. After a bit more looking at the problem, on the principle it had to be the controller, I put a $19.95 Belkin (OPTi chipset) OHCI USB card in, recompiled 2.4.19 for OHCI, ditched the UHCI support, and it's worked properly ever since. > > There seems to be a workaround in userspace driver by adding delay > into read procedure though it affects the connection speed.

If you find anything, I'd love to know, since there are two useless holes on the back of this machine right now.
