Hi, All. I can't get working Adaptec 6805 driver on 9.0 for unknown reason.

I got Supermicro X8DTH-iF based server with two Xeon 5645 (6 cores x 2 thre=
ads),=20
24Gb RAM, Adaptec sas 6805 raid. I downloaded 6805 driver code for FreeBSD =
8.3=20
from adaptec site and compiled it under fresh-installed FreeBSD 9.0-RELEASE=
 (amd64),=20
kldloaded it and got hung and timeouts:

aacu0: <Adaptec RAID Controller> mem 0xf8c00000-0xf8ffffff,0xf8bbc000-0xf8b=

.....

Then I installed 8.3, compiled driver and it started without any problem.=20
After that I cvsup-ed FreeBSD10 code (head, 28.05.2012), compiled it,=20
booted new kernel (set module=5Fpath/boot clang), compiled driver and it=20
kldloaded again without any error (raid6 2.8Tb disk read-write speed good, =

no errors).

Here is kernel 10 aacu driver dmesg lines:

The problem exists only under 9.0-RELEASE. Interrupts doesn't work for this=
=20
device at all. Driver makes device initialization using sync requests and=20
then hungs on first async io waiting interrupt.

Driver interrupts install code looks good:

sc->aac=5Firq=5Frid =3D 0;
if ((sc->aac=5Firq =3D bus=5Falloc=5Fresource=5Fany(sc->aac=5Fdev, SYS=5FRE=
S=5FIRQ,
                                          &sc->aac=5Firq=5Frid,
                                          RF=5FSHAREABLE | RF=5FACTIVE)) =
=3D=3D NULL) {
                device=5Fprintf(sc->aac=5Fdev, "can't allocate interrupt\n"=
);
                return (EINVAL);
}

if (sc->flags & AAC=5FFLAGS=5FNEW=5FCOMM=5FTYPE1) {
    if (bus=5Fsetup=5Fintr(sc->aac=5Fdev, sc->aac=5Firq,
                       INTR=5FMPSAFE|INTR=5FTYPE=5FBIO, NULL,.
                       aac=5Fnew=5Fintr=5Ftype1, sc, &sc->aac=5Fintr)) {
        device=5Fprintf(sc->aac=5Fdev, "can't set up interrupt\n");
        return (EINVAL);
}

I added "panic" call at the beginning of interrupt handler=20
"aac=5Fnew=5Fintr=5Ftype1()" and found it never called during driver=20
initialization on 9.0. Is this 9.0-RELEASE bug or future ?
