Comment 30 for bug 123789

I see that some people reporting this issue have an nVidia IDE controller, while others have an Intel 82801 controller, and there may even be other controllers represented here.

I do not have personal experience with the Intel 82801 controller, but I have seen reports from other users that indicate that the 82801 uses the sis5513 module in older kernels (for instance, Feisty's 2.6.20 series). Any of you that still have working kernels may want to check for the presence of this module in your lsmod reports.

For some reason, the sis5513 module has been disabled in the more recent Gutsy kernels (by the time I first switched to Gutsy, they were already up to 2.6.22.13, so I can't vouch for earlier Gutsy kernels). The module is still in the code, but its been completely shut off so the module is not available.

I know from personal experience, including kernel recompiles, that the kernel code is not yet ready to shut off the sis5513 module. Without this module, my own computer (which has an official SiS 5513 IDE controller) will not boot from either a 2.6.22 or 2.6.23 kernel without the SiS 5513 module -- the computer simply does not recognize my hard drives. But simply enabling this one module brings me back to a working computer.

Cheers!
