From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: I just installed nahant b2 on an SMP i386 system. If I boot to an SMP kernel, once I get past grub, my keyboard and mouse fail to function properly. Strangely enough, input on my keyboard causes my mouse cursor to jump around on the screen in a seemingly random fashion. However, using the UP seems to not cause this strange behavior. Needless to say I was unable to complete the install (complete firstboot) w/o selecting a UP kernel. I have compiled stock 2.6.10 UP and SMP kernels on this RHEL 4 install, and DO NOT get this behavior. dmesg shows the following when grep'ing for 'mouse' when booting the RHEL SMP kernels: [root minerva ~]# dmesg | grep -i mouse mice: PS/2 mouse device common for all mice psmouse.c: Failed to reset mouse on isa0060/serio0 input: PS/2 Generic Mouse on isa0060/serio0 psmouse.c: Failed to enable mouse on isa0060/serio0 psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 2 bytes away. psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 2 bytes away. psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 2 bytes away. psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 1 bytes away. psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 2 bytes away. psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 2 bytes away. psmouse.c: Mouse at isa0060/serio0/input0 lost synchronization, throwing 2 bytes away. Hardware: SuperMicro X5DAL-TG2 motherboard Intel E7505 chipset Version-Release number of selected component (if applicable): kernel-smp-2.6.9-1.648_EL and kernel-smp-2.6.9-1.675_EL How reproducible: Always Steps to Reproduce: 1.Install RHEL 4b2 2. Boot to SMP RHEL 4b2 kernels listed above. 3. Expected Results: Everything to work fantastically, what else? Additional info:
This problem still exists in the current release of Red Hat Enterprise 4. I can duplicate the problem using RHEL 4 on a Dell Precision 530 workstation and the SMP kernel.
We have the same problem on a dual XEON system using an Intel SE7505VB2 board on the stock RHEL4 smp kernel.
Turns out disabling Legacy USB in the BIOS makes the problem go away.
