Hi all,

as yesterday was a bank holiday in Germany I wasn't in the office to
try the patch linked in the email.
Is it consent that I should try the patch located here:

>>>
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/chipsets/ata-intel.c.diff?r1=1.25;r2=1.26

and report the result? Or do you need some additional discussion on
this topic? I really don't know much about ata-intel chipset programming
interface things, that's why I'm asking :-)

Best regards,
Holger

Intel probably don't see issue there, as the same behavior can be found
even on latest chipsets. But according to my ATA specs understanding and
real PATA devices behavior analysis, this behavior is not correct. When
ATAPI device connected to the first of two SATA ports, routed to the
same legacy-/PATA-emulated ATA channel (master device), soft-reset
sequence returns false-positive slave ATAPI device presence. Problem
doesn't expose with ATA disk devices, or if some other device really
attached to the slave port. Problem looks like it was there always, but
before ATA_CAM it was not usually noticed, due to very small IDENTIFY
command timeouts in ata(4).

If somebody can give better explanation or propose better workaround --
welcome, as I am not very like this solution.

As as I can see, ata_intel.c should not change that bit if it was set
for some reason. Theoretically, OOB (Out-of-Band signaling) is the
function of the same state machine which sets that PHY changes status
flag. But friendly speaking, I have no idea what result can be from
setting of this bit. In this legacy/PATA emulation mode there are too
many things not documented to be sure in anything.

With regards to item #1: I don't see anything in the ICH9 errata that
indicates a silicon bug if the only device attached to the controller is
an ATAPI device and connected to SATA port 0 (presumably), or an
odd-numbered port?  If this problem exists on other ICHxx and/or ESBxx
chips, I sure would hope it'd be documented.

I haven't tried confirming it myself, but if need be I can set up a test
box with a SATA-based DVD drive hooked up to it + provide remote serial
console/etc. if it'd be of any help.  I don't think it would be (sounds
like you have lots of hardware :-) ), but I'm willing to help in any way
I can.

With regards to item #2: could this be at all related to OOB (bit 15)
somehow being set in PCS (SATA register offset 0x92)?  I'm doubting it
but I thought I'd ask.  My thought process, which is probably wrong
(consider it an educational discussion :-) ):

The ICH9 specification states that the default value for this register
is 0x, and b15=0 means "SATA controller will not retry after an OOB
failure", while b15=1 causes the controller to indefinitely retry after
OOB failure.  I imagine system BIOSes and other things can change this
default value, but we don't seem to print it anywhere in
ata_intel_chipinit() during a verbose boot.

Looking at chipsets/ata-intel.c, it looks like we only touch PCS in
ata_intel_chipinit() and ata_intel_reset().  In the former, we avoid
touching bits 4 through 15, and in the latter we mask out only what we
want to adjust (e.g. the SATA port per ch variable).

Reference material is 14.1.31 of the ICH9 datasheet:

I see two problems here:
 1. "devices=0x3" means that two ATAPI devices were detected instead
of one. I can reproduce it also with other Intel chipsets. It looks like
a hardware bug to me. It can be workarounded by reconnecting ATAPI
device to even (2 or 4) SATA port, or connecting any other device there.
 2. "DISCONNECT requested" means that controller reported PHY status
change for some device on channel, triggering infinite retry. Unluckily
I have no ICH9 board, while I can't reproduce it with ICH10 or above.

This patch should workaround the first problem in software:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/chipsets/ata-intel.c.diff?r1=1.25;r2=1.26
Try it please and let's see if with some luck it do something about the
second problem.

Ah no, my mistake.
Assuming we have a 512kB buffer
for such messages, then at about two roundtrips per second, only issuing the
WARNING, this would need about 1 hour. For all the detailed messages, it
would reach the same amount in about 10 Minutes. Just went back to the

Hooray.

Dear all,

just a short update on the issue:
I changed SATA setting in BIOS to AHCI and can now boot without problems.
Thanks very much for the hint!

Interesting thing is that only the DVD-drive is directly attached using SATA:
- System Disks are attached using 3ware-controller (mirror, twe)
- ZPool devices are accessed via FibreChannel.

I'll try to provide more verbose info later during the day by preparing the 
current
kernel and including the required debugging settings and then rebooting
with AHCI disabled again - but normal work is currently kicking in again...

Don't upgrade the pool for now, you have problems to solve first.
Then, you'll be able to upgrade the pool, and don't forget to also
update the zfs boot code before rebooting (see UPDATING). Don't forget
you won't be able to import your (upgraded) v28 pool with a
8.2-RELEASE if you have problems with 8-STABLE ! Also, you can use
mfsbsd if you shoot yourself in the foot.

I think this is much more likely related to an ATA/ATAPI-related change
that was committed on April 17th recently and is not related to ZFSv28.
Please see this thread:

* 2011/05/29 -- ICH9 panic/instability on recent kernel
  http://lists.freebsd.org/pipermail/freebsd-stable/2011-May/thread.html#62804

Holger, can you please provide the following two things?

1) Output from "pciconf -lvcb".

2) Full output from a verbose boot (option "5" at the loader prompt).

I imagine #2 isn't going to work for most users because there's no way
to get pages and pages and pages of data from a panic'd machine without
either serial console (which will require a 2nd machine and possibly a
null-modem cable) or properly setting up a dedicated swap partition and
large-enough /var filesystem, plus their kernel would need DDB support
added to it (so they could properly do "call doadump" then "reboot").

A workaround which one user has confirmed is to enable AHCI for your
SATA controller in your system BIOS (if such is available).  ataahci.ko
will be used (which is AHCI via ATA) and your device names probably
won't change.  Alternatively you could enable AHCI and use ahci.ko
(ahci_load="yes" in /boot/loader.conf) to get AHCI via CAM, which
provides NCQ and other features, but your device names will change.
My familiarity with ATAPI is limited however.

CC'ing mav@ here.

Alexander, Holger's report looks exactly like Michael's report.

Possibly we should consider reverting the April 17th commit until we can
figure out what's going on here.

8-STABLE won't boot with ZFSv28

2011-06-01 Thread Holger Kipp
Hi all,
I have a very irritating problem with 8-STABLE and ZFSv28

I upgraded to 8-STABLE as of yesterday (31.05.2011),
downloaded stable-8-zfsv28-20110521.patch.xz
and applied the patch using

cd /usr/src
patch -E -p0 < /path/to/patchfile
make buildworld
make buildkernel KERNCONF=foo
make installkernel KERNCONF=foo
make installworld
mergemaster

which all went smoothly.

After reboot, I only got
unknown: WARNING - ATAPI_IDENTITFY requeued due to channel reset LBA=0
all the time, and then after an hour or so (wasn't on site),
system gave
Fatal trap 12: page fault while in kernel mode
cupid - 0; apic id = 00
fault virtual address = 0x8
fault code   = supervisor read data, page not present
instruction pointer= 0x20:0x80252301
stack poiner   = 0x28:0xff8a7ac0
frame pointer= 0x28:0xff8a7b00
code segment= base 0x0, limit 0xf, type 0x1b
   = DPL 0, pres1, long 1, def32 0, 
gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process   = 0 (thread taskq)trap number   = 12
panic: page fault
cpuid = 0
Uptime: 1h0m13s
Cannot dump. Device not defined or unavailable.
Automatic reboot in 15 seconds - press a key on the console to abort


Needless to say the system did not reboot. Had to powercycle.

Then always got the
unknown: WARNING - ATAPI_IDENTITFY requeued due to channel reset LBA=0
error about once per second.

Have now used a fixit-disk to change back to the old kernel:
FreeBSD 8.2-STABLE #12: Mon Apr 18 12:48:56 CEST 2011
and rebootet.
Now zfs claims to be v28, current storage pool is at 15.I'd love to
try ZFSv28, but with the old kernel I don't think
this is a good idea - but with the new kernel it seems I can't
even boot properly.
Any suggestions as to how to proceed?

Best regards,
Holger
