User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 4.0; Q312461)

Description of problem:
Intel P4 laptop with internal touchpad on /dev/psaux and an external usb mouse 
on /dev/mouse.  The usb mouse is the corepointer and the touchpad uses 
the "SendCoreEvents" option in XF86Config-4.  Both mice work fine, except under 
moderate to heavcy disk usage, the external usb mouse freezes.  The touchpad 
still functions fine.  I can reset the usb mouse by physically disconnecting 
and then reconnecting it.  No change if I use the touchpad as the corepointer.  
Keyboard and screen are not affected in any way.  Only the external usb mouse.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. boot
2. use system as usual
3. do a disk intensive operation ... (i.e. make a big tarball, use GIMP with a 
big image, etc.)
4. mouse will flicker / jump around and then freeze
5. disconnect external mouse and immediately reconnect
	

Actual Results:  external mouse freezes.  Keyboard, screen, touchpad, still 
operate as usual.  After disconnect/reconnect of external usb mouse, it 
functions normally until the next freeze event.

Expected Results:  No mouse freeze at all

Sorry, didn't see this bug, taking now.

Please upgrade to 2.4.20-18.7 (or, for RHL 9 2.4.18-18.9), and verify
that it still fails.

If it fails, I'd like to see three things: output of dmesg, taken
after the failure (please don't drop it into comments box, bug attach instead),
/proc/interrupts and output of lspci (don't -vv it, or attach again).

upgraded to RH 9 three weeks ago.  Both touchpad and usb mouse are 100% 
opertional.  USB mouse no longer freezes.

I have noticed a few other users that have had mouse freeze problems.  One is at

Seems like the guy a URL above has APM issues. I don't think it's relevant.
