Fresh hd.img install of RC2 went swimmingly. Ran fine for maybe an hour,
including getting Crystal CS4235 ISA sound card to play CD's & a couple
MP3's. Had an ordinary user in KDE playing an MP3 off a HPFS mount
(/dev/hda9). Went to VC1 logged in as root. Using mc, went to fat32
mount (/dev/sda5 on sym53c8xx 0,2,0) and selected a dozen directories
full of MP3's, about 1.5 Gb worth. Hit F5 to copy selected to a 100%
freespace 7 GB ext2 mount (/dev/hda14). For a while, sound cut out a
little here, a little there, but mostly kept playing, with file copying
fairly steadily. As % complete started to approach 30%, sound cutouts
started getting really bad, and the mc % complete status started
glitching. Finally, sound quit completely, and very shortly thereafter,
so did the copy progress. Couldn't switch VC's either. Had to hit power
button to recover.

I notice on each boot that tag queuing is set to depth of 16. My SCSI
hard drives only support a depth of 8 (Quantum Fireball; I have at least
a dozen of them), but I've never been able to discover how to change
Linux to accomodate this hardware limitation.

Only one partition failed auto fsck. Got that handled on a manual fsck.
On first pass beyond the initial / fsck, I noticed a message (where
Kudzu should have been) that /dev/psaux was being removed and /dev/ttyS0
added, even though I did nothing with the hardware between boots. The
message seemed to imply I could abort the change, but either I was too
late or couldn't figure out how to stop it. On boot into X login, no
mouse.

I grepped one of the /var/log files and found what follows:

I went on a hunt for lock and lck files, and found a few to delete
without restoring access to the mouse in KDE.

I hunted a bit more and found the contents of /etc/devfs/conf.d on an
8.2 system rather different from 9.0RC2:

file		8.2	9.0
dynamic.conf		 X
modem.conf	 X	 X
mouse.conf	 X	 X
psaux.conf		 X
ttyS0.conf		 X

Contents:
8.2
mouse.conf
REGISTER        ^psaux$    CFUNCTION GLOBAL symlink psaux mouse
UNREGISTER      ^psaux$    CFUNCTION GLOBAL unlink mouse

9.0
mouse.conf
REGISTER        ^misc/psaux$    CFUNCTION GLOBAL mksymlink misc/psaux
mouse
UNREGISTER      ^misc/psaux$    CFUNCTION GLOBAL unlink mouse

psaux.conf
REGISTER        ^misc/psaux$    CFUNCTION GLOBAL mksymlink misc/psaux
psaux
UNREGISTER      ^misc/psaux$    CFUNCTION GLOBAL unlink psaux

Whether the differences have any bearing on this I have no idea. AFAIK
this is nothing but 8.2 v 9.0 differences.

/var/log/kdm.log ends with (and has a bunch more of):

(==) Log file: "/var/log/XFree86.0.log", Time: Mon Sep  9 20:08:05 2002
(==) Using config file: "/etc/X11/XF86Config-4"
Using vt 7

	Device or resource busy.
(EE) xf86OpenSerial: Cannot open device /dev/psaux
	Device or resource busy.
(EE) xf86OpenSerial: Cannot open device /dev/psaux
	Device or resource busy.

I think I eradicated all the lock files, so I don't know why the above.

So, who can tell me why all this happened, and how to make the mouse
work again in X?
