Hi all, I'm having a preblem with a few workstations that are hard freezing from time to time since about a week. Curiously since then we upgraded from 2.6.20.6 to 2.6.20.10... While investigating I found out that there seems to be a problem, occuring randomly on some workstations after a certain amount time, that the mouse gets disconnected continously (see full log attached): Nov 7 00:09:36 mammatus kernel: [22055.357104] usb 2-1: USB disconnect, address 2 Nov 7 00:09:37 mammatus kernel: [22055.596974] usb 2-1: new low speed USB device using uhci_hcd and address 3 Nov 7 00:09:37 mammatus kernel: [22055.777831] usb 2-1: configuration #1 chosen from 1 choice Nov 7 00:09:37 mammatus kernel: [22055.793905] input: Logitech USB-PS/2 Optical Mouse as /class/input/input5 Nov 7 00:09:37 mammatus kernel: [22055.793994] input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-0000:00:1d.0-1 Nov 7 00:10:11 mammatus kernel: [22090.368722] usb 2-1: USB disconnect, address 3 Nov 7 00:10:12 mammatus kernel: [22090.608588] usb 2-1: new low speed USB device using uhci_hcd and address 4 Nov 7 00:10:12 mammatus kernel: [22090.784671] usb 2-1: configuration #1 chosen from 1 choice Nov 7 00:10:12 mammatus kernel: [22090.800881] input: Logitech USB-PS/2 Optical Mouse as /class/input/input6 Nov 7 00:10:12 mammatus kernel: [22090.800982] input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-0000:00:1d.0-1 [.....] Nov 7 17:57:28 mammatus kernel: [86097.543960] input: Logitech USB-PS/2 Optical Mouse as /class/input/input596 Nov 7 17:57:28 mammatus kernel: [86097.544050] input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-0000:00:1d.0-1 Nov 7 17:59:07 mammatus kernel: [86196.161272] usb 2-1: USB disconnect, address 112 Nov 7 17:59:07 mammatus kernel: [86196.401142] usb 2-1: new low speed USB device using uhci_hcd and address 113 Nov 7 17:59:08 mammatus kernel: [86196.577674] usb 2-1: configuration #1 chosen from 1 choice Nov 7 17:59:08 mammatus kernel: [86196.593834] input: Logitech USB-PS/2 Optical Mouse as /class/input/input597 Nov 7 17:59:08 mammatus kernel: [86196.593939] input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-0000:00:1d.0-1 Nov 7 17:59:13 mammatus kernel: [86202.206449] usb 2-1: USB disconnect, address 113 Nov 7 17:59:13 mammatus kernel: [86202.446319] usb 2-1: new low speed USB device using uhci_hcd and address 114 Nov 7 17:59:14 mammatus kernel: [86202.623309] usb 2-1: configuration #1 chosen from 1 choice Nov 7 17:59:14 mammatus kernel: [86202.638402] input: Logitech USB-PS/2 Optical Mouse as /class/input/input598 Nov 7 17:59:14 mammatus kernel: [86202.638493] input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-0000:00:1d.0-1 There are some occasionnal connect/disconnect due to the fact that we recently bought an ergonomic mouse (Evoluent Vertical Mouse 3 Rev. 2) that some people plug-in the workstation they are working for the duration of their day/night shift... but nothing like 600 disconnect / day / workstations? And actually, the source workstation of this log as not yet got the mouse connected to it since it's last reboot. Looking at the changes between 2.6.20.6 and 2.6.20.10 I only found this USB related: http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.22.y.git;a=co mmit;h=0e22438a5adfdf32b3bb1c75c81c01a29fba9770 I'm presuming that maybie eventually it might hit a input max barrier (like a max of 1024) and then the kernel would be crashing? Help very much appreciated! Regards, Vincent Fortier Informatique Environnement Canada
