Yeah, looks like it.  I just sent the patch for #upstream-fixes and will
forward it to -stable once it gets into #upstream-fixes.

Thanks.

I have this patch actually applied and had switched off the computer
afterwards completely for more than one hour two times. Each time it
booted then (this was the patch you suggested initially to Many Maxwell
this month to this list).

Everything seems to work fine, but my dmesg and /var/log/messages is
flooded with this now:

Aug 29 23:20:39 zappa ata1: EH complete
Aug 29 23:20:41 zappa ata1: EH complete
Aug 29 23:20:47 zappa ata1: EH complete
Aug 29 23:20:49 zappa ata1: EH complete
Aug 29 23:20:51 zappa ata1: EH complete
Aug 29 23:20:53 zappa ata1: EH complete
Aug 29 23:20:55 zappa ata1: EH complete
Aug 29 23:20:56 zappa ata1: EH complete
Aug 29 23:20:59 zappa ata1: EH complete
Aug 29 23:21:01 zappa ata1: EH complete

I am curious if it boots tomorrow after sleeping for one night :-P

Hmm... Can you post full dmesg output?  We used to see things like above
when ATAPI CHECK SENSE handling somehow failed to tell EH that it was an
exception not worth whining about.  Maybe EH action mask is not being

Of course :-)

dmesg is attached with patch applied. At the end of the patch it (of
course) continues, but only with:

ata1: EH complete
ata1: EH complete
ata1: EH complete

Hmn, to take my pants down entirely: What is this "EH"?

And how does the change of the .reset function affect this? May be, I

You are right, it started immediately without a hitch this morning after

I'm seeing a similar problem after upgrading from 
2.6.25.14-108.fc9.x86_64 to 2.6.27-rc6.

From what I can tell the messages
Sep 23 10:27:20 pangw kernel: ata6: EH pending after 5 tries, giving up
Sep 23 10:27:20 pangw kernel: ata6: EH complete

are printed for a disconnected ATA port that's a neighbor
of one that's occupied.

these are the ports that are in use:
Sep 23 10:19:40 pangw kernel: ata1.00: ATA-6: ST3160023A, 3.01, max UDMA/100
Sep 23 10:19:40 pangw kernel: ata2.00: ATAPI: _NEC DVD_RW ND-3550A, 1.05, max UDMA/33
[PATA]
Sep 23 10:19:40 pangw kernel: ata5: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

The WDC drive was previously on ata3 and the message were then printed
for ata4.  This makes me thunk it might be related to managing of
dual-ported sata_nv chips?

before:

Hey, I did not realize this yet!

My only SATA device seems to be connected to Port2:

Sep 24 07:12:47 zappa ata2: SATA max UDMA/133 cmd 0xe80 ctl 0xe00 bmdma 0xd808 irq 21
Sep 24 07:12:47 zappa ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)

Sep 24 07:12:47 zappa ata2.00: configured for UDMA/133

Whereas my message log is still flooded by ata1 stuff:

Sep 21 11:34:57 zappa ata1: EH complete
Sep 21 11:34:57 zappa ata1: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen

Sep 21 11:34:58 zappa ata1: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen t2

Tijo, is there any stuff I should try out? I mean, if I got this right,
the boot problems itself were fixed by removing nv_hardreset, but is
there a way around getting the log flooded by "EH complete" now?


Kind regards, Konsti

Well, this Patch simply installs the old weird behaviour with the
result in sometimes no cold boot possible yielding into

ataX: link too slow to response ...
ataX: COMRESET failed (errno=-16)

After that powercycle required. I wrote it down from memory. If there
is a detailed log required I can create them tomorrow when I have my
Hands back onto the machine.

just to make sure it's not some bad coincidence.

Hello!

The patch before, I told it always boots but the last two days I had
much difficulties to boot. It was hard resetting and waiting a couple of
times before bailing out with no mountable root FS. 

One time it was switched off three hours and the next time overnight, I
powercyced a couple of times. If I am the only one experiencing this
difficulties (am I the only one with this chipset/revision reporting?),
shouldn't we consider this machine... broken? I change SATA cables from
time to time, but these seem all to be okay. I mean, if it is really
_that_ strange...


I fetched 2.6.27 now and tried this patch. A short powercycle, reboot
wasn't a problem yesterday, this morning also not, so looks well so far,
tihs is how /var/log/messages looks now:

Hello Tejun!

After my short reply I had a 2.6.27 running with

[-- Attachment #2: sata_nv-nf2-hrst-debug-take2.patch --]

fine so far. It bootet immediately at any time I powercycled the
machine. Hot, cold and reboot seems to be no problem, no
/var/log/messages flooding also.

I just wanted to inform you, whatever the investigations result into, on
_my_ machine this incarnation is just fine.

Regards, Konsti

It's a different failure on a different controller.  Can you please
file a bug report on bugzilla.kernel.org and...

1. Reproduce the problem with kernel-2.6.28-rc8.
2. Attach boot and the failure kernel log.
3. Attach the output of "lspci -nn".

Thanks.

Yes, with 2.6.25 it always had a clean booting system.

From time to time I do an update and with some 2.6.26_rcX I had
problems the system not solving a cold boot sometimes. Long I suspected
a hardware issue but one time I went down to 2.6.25 and the problem was
away. 

Then I updated to 2.6.27_rcX because I was hunting down some nfsv4
error, considering this as a bug or an issue in front of screen. Then I
realised the cold boot problem again which I almost forgot meanwhile or
considered closed from 2.6.26_rcX over 2.6.26 to 2.6.27_rcX.
