I have a system that uses sata_via and sr_mod for my cd-drive. This causes the following problem:

This occurs when using the sata_via and sr_mod modules. i have proven it is these modules as ide cd-drive using ide_cd on the same system do not produce these errors, but ide drives using the sata_via and sr_mod modules do.
SATA CD drives use this driver and cause the same problem. I have used dedicated SATA cd drives (panasonic UJ875A) and also ide-drives with sata adaptors. Both produce above errors.
Unfortunately these error are common but I cannot reproduce them - they just happen!
I need to use SATA drives reliably but this is causing me concern.
A solution would be for me to force sata drives to use ide_cd. However i dont think this is possible or dont know how to do it. Any ideas?
The best answer would be to solve the source of the problem - any thoughts there?
I am using 2.6.29 Kernel after upgrading from 2.6.22 (both exhibit same issues)

cables/ports
have you tried exchanging the sata cables? does your board have more sata ports and can you connect the cd-drive to another port? have you tested with just the cd-drive on this sata adapter (and the hd on another adapter, possibly pata) to check if this is a problem with cd-drives or with multiple devices on one sata adapter instead?
i have tried all the above.
i have tried all the above. This happens on various machines and various makes and models of hardware. the only common attribute is the sata_via module. The error also occurs when using this module with a pata cd drive. The cables have been changed and ports have been changed. Tried using just one cd writer instead of two. I can run the system with two pata writers and one sata harddrive with no error AS LONG as the system is setup to use ide-cd module.
Therefore I am convinced with all the testing and the numberous combinations that I have tried that it is a problem with sata_via (or sr_mod). But I do NEED to use sata cd drives.
The only thing that I havent tried for long periods is a new motherboard with different chipset (I tried an intel-atom board with no errors for a short period - but it didnt have all the feautres on the motherboard that I needed).
Is there any way of getting a sata cd drive to run on ide-cd?
Or any known fix for the emask timeout issue as shown above?
Thanks,
Conor
Sata_via still problematic
I still have not come to a conclusion about this fault/bug/error.
Does anyone have any ideas?

I seem to have the same
