[parisc-linux] C100 improvements, problems

[Greg Ingram]

Howdy ya'll,

Failing to read all the new messages first, I did a cvs update and wound
up with unbuildable source.  So I kept the sim700 bits and unrolled the
20010124 tarball.  Now I've got my disks back.  Thanks.

Current problems:

o  I still get the 'Warning: unable to open an initial console.' message.  
Serial is working better and I get kernel messages on the serial console.  
init is running a getty on /dev/ttyS0 but I never get a login prompt.  
I've tried with and without 'console=/dev/ttyS0' as a kernel commandline
parameter.

o  I still have trouble with unligned data references.  I've discovered
that in addition to tar and make, sleep and nscd also produce this error.

o  I see a curious message when I reboot:

	Trying to free nonexistent resource <ffd07000-ffd0700b>

o  more page faults when I use SCSI but not when root is mounted via NFS.  
Hmm... why could that be?  I thought maybe it had to do with swapping, but
if I use nfsroot and then:

	# swapon /dev/sda2

more works fine.  I can mount the ext2 partition and run more from there.  
But when the SCSI disk is root, more page faults. Here's some kernel
messages:
 
	do_page_fault() pid=285 command='more' type=15 address=0xbaffffff
	vm_start = 0x4018c000, vm_end = 0x40190000
