ata software reset..question

I get the error ata1 software reset failed (device not ready)  There is a lot of talk
about this bug all over google.  Reading the gentoo forums it seems it is an error
with pmp in the kernel which is sata port multiplyer, which allows for daisy chaining sata ports
like you can with a usb hub.   If you configure the kernel without this support the error goes away.

So my question is, is there a way to go into the kernel that is installed with installation and do a
make menuconfig on this kernel?? ( didnt have much time to research this just looking for a quick answer
im at work )

No, you'll need to reconfigure and recompile the kernel from ABS.

Do you know what to change in the config to disable this feature? I have had ata1 software reset + emask timeout problems with a DVD burner and this may be the solution. And it seems there are several using Arch who are having this problem as well.

Could you post a link to the gentoo thread as well?

Here is the link http://forums.gentoo.org/viewtopic-t-76 … t+pmp.html

The posts towards the bottom state this:

-so as you pointed, i re-compiled my kernel with pmp off (CONFIG_SATA_PMP=n )
everything goes to normal now.

-almost nobody has pmp hardware installed. It is one of the options 99% of the users can disable.
