Good morning, everyone!

There seems to have been some changes made concerning the supported
Promise controllers.

I have a SATA TX2Plus (PDC20775 chip). This is a sort of hybrid for SATA
and PATA - it can run two drives of both.

Until today I got this running with a sort of hack I found here:
http://www.mail-archive.com/freebsd-hardware@freebsd.org/msg00553.html

That worked fine until today. Now the PDC40775 (which is supposed to be
the same device if you believe google) has the same ID and the
controller is identified as such. The result is this (in dmesg):

ad8: req=0xc398a000 SETFEATURES SET TRANSFER MODE semaphore timeout !! DANGER Will Robinson !!

Along with a crash of a process that couldn't even be stopped by a
kill -9!

Can someone tell me how to fix this?

Regards
Chris
