One thing of interest could be the answer I get when I 'camcontrol
rescan all':
ahcich0: Poll error on slot 0, TFD: 04d1
Any chance to get ahci.ko working with that SB700 controller?
I found out that it doesn't seem to be a problem of the specific
chipset, but ahci.ko with that specific HDD.
Doing some searches for my HDD model lead me to that PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=152817
It describes exactly my problem and I thought that there's also a
solution available:
I took the patch mentioned as "committed to head" in the PR
(http://svn.freebsd.org/viewvc/base/head/sys/cam/ata/ata_xpt.c?r1=215454&r2=217444&pathrev=217444&diff_format=u)
and applied it to RELENG_8_2.
Unfortunately I'm still getting the TFD: 04d1 ahcich Poll error and the
disk isn't seen.
What's my mistake?
Ok, me again, for the records, it seems the committed patch is missing
some relevant lines from the PR-discussion.
I additionally applied the following, which makes the disk usable:
--- src/sys/cam/ata/ata_xpt.c (revision 217514)
+++ src/sys/cam/ata/ata_xpt.c (working copy)
@@ -775,7 +775,8 @@

- } else if (softc->action == PROBE_SETPM&&
+ } else if ((softc->action == PROBE_SETPM ||
+ softc->action == PROBE_SETDMAAA)&&
status == CAM_ATA_STATUS_ERROR) {
goto noerror;
}
Alike patch was committed to HEAD at r217875 and will be merged to
8-STABLE soon.
Will there be a errata for 8.2 regarding that issue?
Anybody unpacking a HP N36L will probably think the controller is not
working...
IMHO it should be errata for HDD, not for the system.
