pata_sis:sg_write errors

pata_sis:sg_write errors

[Jordan Neumeyer]

Well recently I've been using libata since my my distribution offered it when
they switched to 2.6.19( maybe? 18) in the initramfs image.  I have a sis 5513
controller, which after a couple of days started acting up and coming up with
the following error:

sg_write: data in/out 30576/30576 bytes for SCSI command 0xbe--guessing data i$;
 program grip not setting count and/or reply_len properly
printk: 319 messages suppressed.
sg_write: data in/out 30576/30576 bytes for SCSI command 0xbe--guessing data $n;
 program grip not setting count and/or reply_len properly
printk: 321 messages suppressed.
sg_write: data in/out 16464/16464 bytes for SCSI command 0xbe--guessing data $n;
 program grip not setting count and/or reply_len properly
printk: 323 messages suppressed.
sg_write: data in/out 16464/16464 bytes for SCSI command 0xbe--guessing data $n;
 program grip not setting count and/or reply_len properly

sg_write: data in/out 16464/16464 bytes for SCSI command 0xbe--guessing data $n;
 program grip not setting count and/or reply_len properly
printk: 324 messages suppressed.

It's repeated over, and over; differing amounts of bytes.  I'm unsure what
invoked such errors, because it only started to happen a few days after use of
the kernel.  Which was 2.6.19-beyond kernel.  I don't believe any additions made
by the beyond kernel affected the libata system.

Has this been fixed in the 2.6.20-rcXs?

This is not a kernel bug.  The SCSI midlayer is bitching that grip
hasn't set certain parameter while using the sg interface (which
previous kernels have ignored).  grip should be updated to use proper
parameter.  So, no, 2.6.20-rcX won't fix it.  You need to update grip.

Hi
Thank you for your help.  So all I need to do is update the sg3_utils?
 It's the only package I can find dealing with sg and scsi? And do I
have to set this parameter or is it automatically set?  I've never
dealt with this scsi system, because all I have are pata disks.  No
sata nor scsi.

You need to update grip, cd ripper.  And, it's not something a user can
change.  The program itself needs to be updated.  So, bug the grip
developers.  The messages are just notices to let people know that those
programs need to be updated and can be safely ignored for the time being.
