I've had this same problem since Fedora Core 2. SMP kernel doesn't see mouse or keyboard, UP kernel does. Booting with kernel option "usb-handoff" (in 2.6.9 and up, I think) fixes the problem. 2.6.10-741-smp definitely works on my systems provided the "usb-handoff" option is given at boot time. *** This bug has been marked as a duplicate of 123535 *** How do I add this "usb-handoff" option? Where do I place this statement? In Grub? Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a4) Gecko/20041017 Description of problem: Keyboard and mouse are both "dead" upon completion of boot. Kudzu complains that keyboard has been removed. Machine is alive and I can log in via ssh. "/sbin/shutdown -r now" hangs after "Restarting System" Booting with "acpi-off" does not fix the problem. UP kernel works as expected. Version-Release number of selected component (if applicable): kernel-smp-2.6.9-1.639 How reproducible: Always Steps to Reproduce: 1. Install 2. Boot smp kernel 3. Actual Results: Keyboard and mouse are both dead after boot completes. Kudzu can't find keyboard and offers to remove it. Typing various keys results in random movements of mouse cursor on graphical boot screen. Mouse completely dead, no lights on (MS optical mouse), unresponsive. Expected Results: Keyboard & mouse should work. Additional info: Systems (2 different ones) are both Tyan S2665 motherboard with i7505 chipset and dual Xeon (2.4 GHz stepping 9) processors. Hyperthreading is enabled. I can reproduce the problem on an older board if I enable legacy USB support in the BIOS. Unfortunately the newer CPUs want a newer BIOS revision to satisfy microcode requirements and the new BIOSes do not have the option to disable legacy USB support. I see the following messages from i8042.c in the output of "dmesg": "Failed to disable AUX port, but continuing anyway... Is this a SiS?" "If AUX port is really absent please use the 'i8042.naoux' option" After completion of boot, /proc/interrupts does not show anything assigned to i8042 (expect 1 and 12). I recompiled the kernel after activating Alan Cox's i8042 patch but the keyboard/mouse are still dead. I also tried explicitly calling i8042_spank_usb() after the "AUX port" messages and the reboot problem is gone but the mouse and keboard are still dead. Adding printk's throughout the spank_usb() function seems to imply that it never finds anything to disable (comes out with addr=0 and i==PCI_ROM_RESOURCE) Compiling the kernel with voluntary preempt disabled has no effect either.
