Hi - we are running a turnkey system that uses Centos 6.6, Kernel 2.6.32 which we can patch but not upgrade.
Because we need to run it in a separate room from the operator we have installed a KVM extender over cat5 from ATEN - which works very well until we discovered that it was spewing messages into /var/log/message at a terrific rate eventually filling the disk partition. We have a workaround by rotating the log a bit more often but would like to find a better solution.
The message is kernel: usb 2-1.3: input irq status -75 received
First off, a way to suppress the messages and replacing them with "last message repeated nnnn times" would be good.
A proper fix would be even better
Searches suggest a problem with fwupd (which we don't have)
The most promising fix I found was this
https://bugzilla.redhat.com/attachment. ... ction=diff
but I wouldn't know how to apply such a fix. Can someone advise me please.

Re: ATEN CE100 USB KVM Extender
You're probably using rsyslog to write to the logs so a new .conf file dropped into /etc/rsyslog.d/ telling it to ignore a pattern should work. Something like
followed by a service rsyslog reload
However, what is the output from the command uname -r so we can see how back level your kernel is. Maybe this is something that's already been fixed in a newer 2.6.32 kernel.
Code: Select all
if $msg contains "input irq status -75 received" then stop

The future appears to be RHEL or Debian. I think I'm going Debian.

Re: ATEN CE100 USB KVM Extender
Hi - thanks for the reply
There are no files in /etc/rsyslog.d but /etc/rsyslog.conf does exist so I will add at file ATEN.conf with the contents that you suggest.
uname -r gives "2.6.32-504.16.2.el6.x86_64"

Re: ATEN CE100 USB KVM Extender
So "2.6.32-504.16.2.el6.x86_64" is a 6.6 kernel from 2014 so you are about 4 years behind on fixes. It's possible that this is a problem that has been fixed in the newer kernels - latest for el6 is 2.6.32-696.20.1.el6.x86_64 and is available via a yum update.

Re: ATEN CE100 USB KVM Extender
Hi - thanks. There lies the problem. We have no network access on this machine. Is there any other way to get it?
Re: ATEN CE100 USB KVM Extender
This looks like something you should take up with the vendor.
