Ughh, if I knew that 3 days eralier....

First, thank you very much for wour work, but since I couldn't get a promise 
Fasttrak100 tx2 over the weekend (which is very well supported by Sørens 
ataraid) I replaced my sil0680 with a hpt372 and played with the original 
HighPoint drivers (http://www.highpoint-tech.com/USA/b372.htm#FreeBSD) and 
although the module I'm using is for 4.9, it works flawlessly on 4.10-stable. 
Via sysctl hpt37x2.status you can use all functions like with the bios, also 
auto rebuild et cetera works perfectly. (alias raidinfo 'sysctl 
hpt37x2.status')
The main reason why I couldn't use the hpt37(2) with 4.10 was that if one 
drive fails, ataraid removes the drive from the raid configuration. If now 
the same drives returnes (like it happens sometimes after a reboot) you have 
two (ar0 and ar1) arrays. Now you have to know which drive failed and which 
one the controller reports as remaining drive for the original array and dd 
(if=/dev/zero of=/dev/ad? count=63) the opposite drive.
Otherwise the system ends up in booting from ar0, which in my case was the 
"failed" disk, returning after a reboot, and so I had a inconsistent several 
weeks old system.

Your patch my be great for all sil0680 useres but hpt370 users really should 
use the manufacturers driver. You can see a dmesg with them at

Best regards,
