Hello.
I currently have FreeBSD 8.3 on my home server and it works fine but it's
time to upgrade at last (new ath and new ipfw especially allure me). I've
decided to go straight to 10.0 and reinstall system from scratch to purge
all legacy unrelated configs and other stuff.
The problem I faced is as follows. I have a (rather old) motherboard with
integrated SATA controller that presents in the OS as IXP700. In 8.3 it
works fine. I have 2 disks attached to it: one with all my data and
another
one destined to be new system disk. I also have one IDE disk installed
that
is currently used as system disk.
When I booted from USB stick with 10.0, I couldn't see any SATA disks in
the system. I dug into dmesg and found this:

As it seems AHCI controller or disks are not responding to commands and
timeouts eventually.
A friend suggested to try CURRENT image. I went
with FreeBSD-11.0-CURRENT-amd64-VT-20140222-r262336-mini-memstick.img and
got almost the same error: http://pastebin.com/0iGaSWUD
The error repeats and never stops (looks like CURRENT images have
different
config) but it is essentially the same.
I've googled the problem but found only notes about how IXP700 is really
bad and pointers that cabling might be the problem. But I have absolutely
no problems with 8.3, so it looks like some regression during further
development (shift to CAM, maybe?).
Please help me to identify and fix the problem.
This is just a shot in the dark, I'm not familiar with the AHCI driver,
but since you seem to be loosing interrupts (or I would say so based on
the timeout messages), you could try to disable MSI/MSI-X and fallback
to PCI intline IRQs. Could you try to boot with
hw.pci.enable_msix=0,hw.pci.enable_msi=0?
A flood of RC news in my feed forced me to get back to upgrading my
homeserver.
I've tried out 10.1-BETA2 image and got the same results.
Then I've tried to provide these options you suggested, and although there
were some hickup (HDDs didn't respond well at first, I guess), I got to
bsdinstall prompt. Thank you very much for suggestion!
Now I wonder what would be the impact of having these options disabled
permanently. Will there be a huge slowdown of all PCI cards? Or
should it be negligible?
