From Bugzilla Helper: 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 Additional info: Compaq EvoN800c Notebook Intel P4 Mobility 1.7gHz 512MB RAM 40GB HD ATI Radeon Mobility Graphics Card (64MB RAM)
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 http://www.brokedown.net/~squash2/n600c.html
Seems like the guy a URL above has APM issues. I don't think it's relevant.
