From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020913 Description of problem: If a USB mouse is installed, touching the touchpad causes the keyboard to lock up hard (it can only function again if you reboot the computer). The USB mouse continues to work fine. The touchpad never moves the cursor. I am running Psyche on a Dell Inspiron 5000 with a Celeron 500 MHz and 128 MB ram. This is probably related to Bug 70696 for RH 7.3. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Boot with USB mouse plugged in 2.Touch the built in touchpad 3.Observe that the keyboard is frozen. Actual Results: The keyboard is frozen. Expected Results: The keyboard should have continued to function. Also, when I had entries for "/dev/mouse" and "/dev/input/mice" side by side in XF86Config, the touchpad and USB mouse should both have been functional. This worked under RH 7.0. Additional info: When I boot with a USB mouse plugged in and it's autodetected, the USB mouse works fine. However, the second anything touches the built-in touchpad, the keyboard locks up, whether or not X is running. Under X, the USB mouse continues to work perfectly, but the keyboard no longer functions even after one exits X and returns to the console. Only rebooting seems to restore the keyboard function. I edited XF86Config, unplugged the external mouse and rebooted. On the reboot, I changed the mouse configuration to "generic 2-button mouse". The touchpad then worked fine (obviously the external mouse did not) and the keyboard did not lock up. I then tried switching back to the USB mouse with the built in redhat mouse config tool but that led back to the original problem. I tried the kernel that shipped with Psyche as well as the -19.8.0 updated version, and they both behaved the same way. I have not tried using a PS/2 external mouse instead. I'll email again once I do. Hope this is helpful.
Well known bug, unfortunately upstream is indiffirent, because the problem is in Dell BIOS. I have a workaround for this, which removes the workaround for Dell C600 and creates a generic case for C600 and I5000.

Do not dup onto 70796, that one has no data. There was another one though, I'll try to find it.
L.L, would you mind to attach the output of dmidecode? Please do not drop it into the comments box. I'm not sure we'll need it, but let's have it just in case. The dmidecode is a part of kernel-utils RPM.

User mode workaround exits. Make sure that the X11 is configured to open both /dev/psaux and /dev/input/mice, instead of switching back and forth with mouseconfig. Verify it with looking at /proc/interrupts, the IRQ 12 must be in use.
