Willem,
I can only guess, but...
Is AHCI enabled in the bios? If you are not using 'fake-raid' for any
disks, you should [depending on FreeBSD version, HBA, etc.] probably
enable AHCI. Some servers actually come with SATA set in IDE mode. And
if you are using zfs, the controller optimally should not be RAID at
all. And if you have AHCI enabled already, try disabling it (losing hot
swapping ability, and some performance).
ACHI is enabled otherwise I cannot used the last set of SATA connectors
with this MB. Controller for these connectors is CH9.
What version of FreeBSD are you using? I had a terrible experience with
ZFS on FreeBSD 8.2 release, and 8.2-stable-April2011. I would recommend
upgrading to the latest 8-stable with cvsup.
I'm at most 1 month behind on STABLE, since I just upgrade in about that
frequency... Might vary a little on the amount of rumbling on the list.
This thread seems related:

The guy was using 8.2 release, and he downgraded to an old version of
the driver to fix, saying that a patch also existed in 8-stable that
fixes the problem.
Are you using an expander?
No SATA expanders...
What HBA / hard disk controller are you using?
A combi of CH9 and ARECA in PCI-X, disks are all exported a single disks.
Thanx for the suggestions....

Hi,
I'm getting these:
Nov 16 16:40:49 zfs kernel: ata6: port is not ready (timeout 15000ms)
tfd = 00000080
Nov 16 16:40:49 zfs kernel: ata6: hardware reset timeout
Nov 16 16:41:50 zfs kernel: ata6: port is not ready (timeout 15000ms)
tfd = 00000080
Nov 16 16:41:50 zfs kernel: ata6: hardware reset timeout
When inserting the tray with a SSD disk connected to that controller.
Which is probably due to a BIOS upgrade....
At least it started after upgrading the BIOS. So I'm asking SuperMicro
for an older version.
When this happens, the system sometimes panics, haven't written the
details yet down right now. somewhere in get_devices...
After the panic I really need to powerdown the machine, otherwise it
boots but stalls at finding any disks. It does not just find no disks,
it "freezes" at the point it should report the found disks in the
bios-boot.
So apparently the ata controller are left in a very confused state.
Why is the controller found at boot, and works as it should.
And why later it just starts generating these hardware resets??
