I'm afraid that sysinstall is only meant to be run in single-user mode
when you're using it to play with disks after installation.  Yes,
it's not right, but the current probing expects that anything it
can open is there, and otherwise not.

There are some flaws to this technique, the first 2 of which are at least
documented in the installation guide:

	1. If a CDROM isn't in the drive at sysinstall time, it
	   doesn't see it as there.

	2. If a tape isn't in the drive, same thing.

	3. If a disk has things mounted on it then the open will
	   fail and it will treat the error the same way.

For now, I really recommend treating sysinstall as a "one shot" for
installing the system and not for post-install configuration.

This WILL be fixed for 2.1, I just need to go to a totally different
kernel device discovery method and that's going to take a little
time.. :(

As to your other problems, I'm not sure.  Does it still happen
if you disable your cache?  If so, I suspect misconfiguration
or bad cache/DMA invalidation on your motherboard.
