Hey all, I'm looking for some information on a problem i'm not sure =
where to take from here. Basically i've got a 50 pin scsi 2 cdwriter =
that when accessed causes sg kernel errors. Otherwise the system works =
just fine and can even write cds ( although sometimes it hangs ) Here's =
some basic info
in dmesg:

And here is the error itself that has stumped me, a simple " cdrecord - =
eject " can generate it. It happens as soon as the command is issued

Anyone know why this happens? How to fix it.... where to look? I'm just =
starting here, i'm not totally sure its even a scsi problem.
