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):

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!

People are going to want to know if this is still happening in 2.6.23
or 2.6.24-rc2, please.

I andrew,
(logged-in at wrok to make proper reply)
It might be tricky to test properly on 2.6.23.1 since theses are all operationnal aviation forecaster workstations 24/7 .... And sadly the problem only occur on a few of theses workstations AFAIK randomly ??? Actually many of them did not had any problems using the exact same FAI reinstallation using the same hardware..?!?!.
If someone thinks that the problem might effectively be the usb patch that I mentionned before (or any other patch that might make suddently thoses stations to freeze dur to a change that occur between 2.6.20.6 and .10) I would then be able to push a new kernel on thoses workstations without the offending patch(es) and have a clear answer within a week.
I also need to mention that our 2.6.20.6 build contained CFS v20.5 and the new 2.6.20.10 build contains CFS v22 although I doubt it is the cause of the freezing problem but hey, never know. Although I could probably rebuild and push a new 2.6.20.10 without CFS to be sure.
I'm also currently following the problem occurring on a station and I hope it will freeze at an evident input entry. Here where it is now:

I have no idea what might be causing your problems, however that
particular patch you found seems most unlikely to be connected.
One reasonably non-invasive way to do more testing is to use usbmon to
record those multiple disconnect events. Instructions are in the
kernel source file Documentation/usb/usbmon.txt.
