I am having problems with kernel 2.2.3 and my SCSI chain.
I am fairly certain that there is nothing wrong with the hardware
as windoze :( is capable of using it error free.
I have a plain vanilla 2.2.3 as downloaded from ftp.kernel.org and
I have been unable to use the SCSI chain for a while now :(
I have included all the relevant data below from a simple test which
shouldn't have failed by rights.
----
What I did...
1. Inserted a data CD (M$ Visual studio iirc)
2. ran dd if=/dev/sr1 of=/otherdrive/cdimage.large
----
What happened...
1. dd ran for about 600Mb
2. dd gave "Input Output Error"
3. dd terminated
4. SCSI bus reset
----
Here is the all the information which I consider may be at all helpful...
