--- Comment #2 from Yudi <yudi....@gmail.com> ---
I just want to update my original post it had some inaccurate info.
First, this bug is present in v9.3 as well as v10.1 but NOT in v11.
I have added the following to /boot/loader.conf but did not resolve the issue:
"hint.atapci.0.msi="0" (also 1)
"hint.atapci.1.msi="0"
"hint.ahci.0.msi="1"
I even tried rebuilding the kernel but looks like it did not fix the issue.
Well, this was my first time building a custom kernel, so I am not sure I got
this right.
the steps I followed were:
I used the LINT config instead of creating my own,
# svn checkout svn-mirror/base/head /usr/src
# cd /usr/src/sys/amd64/conf && make LINT
# cd /usr/src
# make buildkernel KERNCONF=LINT
# make installkernel KERNCONF=LINT
one of the replies I receive on the mailing list suggested this is not the
right way to rebuild the kernel. He said I was using v11 source files to build
the kernel for v10.
I dont think that was accurate. Can someone please explain how I can apply the
patch.
Bit of info on the system,
the Hitachi drives are in a 2-way mirror connected to 3Gbps SATA ports (AHCI
mode) which I am not using until I fix this issue. OS is installed on the
samsung drives (2-way mirror) connected to 1.5Gbps SATA ports running in IDE
mode (cannot change this to AHCI without installing a hacked version of BIOS
which I dont want to do).
I would greatly appreciate any advise on how to fix this issue.
Below I added some output from the system that might help.
