Hi Steve, I should have been more clear, sorry! You cannot just replace a .ko file that is a binary file. You have to install the kernel sources, then go into the directory that the driver .c and .h files are, back those up, and replace them, then recompile the kernel.
Here's probably what you want to do: Go to here: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/ examine the files. For example, assume it was ata-disk.c Examine the history by clicking on the file you will see the different changes. For example according to this revision 126.96.36.199 was used for 6.2-release, revision 188.8.131.52 was used for 6.1-release. If the bug is in this file it was introduced in one of the intermediate revisions between these 2. You will note this cooresponds with: /sys/dev/ata on your system assuming you installed the kernel sources. If you wanted to backrev this driver you would install sources, recompile the kernel and install it and reboot to make sure you know how to build a running kernel, then you would go to this directory, replace the file you want (ata-disk.c for example) and recompile the kernel and install it and reboot and cross your fingers. Rebuilding the kernel is covered in the online handbook on the website. It most likely won't work the first time. You will need to try this with several files. You also want to try newer revisions of this file. Or you can get bold and tar up the entire directory from a 6.1-release system and move /sys/dev/ata to /sys/dev/ata.bak and untar the old directory into your 6.2 system than try that. Obviously you need a 6.1 system around for this. If Soren has a guess to this he may send you patches to one or more of these files for testing, you will need to apply them and rebuild and reboot to see if it works. This sort of thing can take a lot of time. But it is really critical that you get on it right away. Since right now there wern't many changes between the drivers and it will be very easy to narrow it down to precisely what revision change causes the problem. It is much worse when people post things like such-and-such piece of hardware worked under FreeBSD 2.2 5 years ago and not under 6.2 today.
