Which 2.6.11 kernel is on the Knoppix 3.8.1 CD?

[tvoverbeek]

The Knoppix 3.8 from LinuxTag contains 2.6.11-rc3 according to the information on heise.de.
I have strong indications that on Knoppix 3.8.1 it still is 2.6.11-rc3 and not the 'real' 2.6.11.
I have a problem with a libusb based program with the same symptoms (usb_bulk_write fails
with ENODEV) as a kernel bug present between 2.6.11-rc1 and 2.6.11-rc5 when I run my
program under Knoppix 3.8.1.
When I try with the 'real' 2.6.11 kernel my program works.
Can anybody confirm that the kernel on Knoppix 3.8.1 is 2.6.11-rc3?

For what it's worth, uname -r reports 2.6.11, Would it help to see the size and timestamp?

I did some more investigations on the kernel version on the 3.8.1 CD.
The kernel identifies itself as (uname -a output):
Linux Knoppix 2.6.11 #8 SMP Sun Mar 20 21:09:51 CET 2005 i686 GNU/Linux
The kernel is part of a custom version of the Debian kernel-image-2.6.11 package.
The first Debian version of kernel-source-2.6.11 is later: 2005-03-21. So probably Klaus (?) used
the kernel source directly with Knoppix specific patches included.
The Knoppix 3.8/Cebit 2005 version was based on 2.6.11-rc3 according to the article (in German)
on www.heise.de/ct.
My guess is that we still have the same version in 3.8.1.

My problem with usb_bulk_write in libusb was introduced with kernel Changeset 1.1938.455.15 on 2004-11-27
and solved with Changeset 1.1982.126.8 on 2005-02-25. See the kernel Bitkeeper logs on
linux.bkbits.net. This corresponds to 2.6.11-rc1 to 2.6.11-rc5 inclusive.

So my question remains:
Can anybody confirm that the 2.6.11 kernel of Knoppix 3.8.1 is derived from one of the 2.6.11-rcx versions?

This is from a recent apt-get kernel-source-2.6.11

[kernel-source-2.6.11]# cat version.Debian
2.6.11-3
[kernel-source-2.6.11]#

Do you believe what you read?

I got kernel-source-2.6.11 myself.
The kernel on the Knoppix CD is a custom kernel made with kernel-package.
When the 3.8 (Cebit 2005) version was released it was based on 2.6.11-rc3 (version from
www.kernel.org). I am pretty sure it has not changed for 3.8.1. If I use kernel-image-2.6.11
mu libusb problem goes away.
