Comment 32 for bug 228624

I have same problem. all_generic_ide does fix. The only notable change i could find is upon adding that to kernel line udma mode is now set to 2 instead of 4 which is what i believe someone above said? Since this only happened when i upgraded the kernel and using an old kernel fixes it then it is likely to be a regression in kernel? Has anyone tried compiling the latest kernel and seeing if that fixes? (I'm not going to attempt because last time i tried compiling a kernel i got lost :p )
