[Repost] Ultra2 SMP freezes with heavy disk I/O

[Repost] Ultra2 SMP freezes with heavy disk I/O

[mt1]

	Hello,

	I have posted this message yesterday but I don't see it on the mailing list.
	Sorry for the inconvenience if you see it twice...

	Today, I have tested hardware with diag-switch? and diag-level true and
	a serial console. Nothing to declare...

	Original message:

    Hello,

    A, U2 (2 GB, 2 UltraSPARC-II, 2 73 GB SCSI disks [raid1]) is running
	Debian/testing with 2.6.20.3 kernel. This station is used as mail server
	and I have seen some freezes. When it freezes, sysrq or stop+A do not
	work (not panic nor Oops, only freeze).

    I have tested 2.6.18 (from debian), 2.6.20.x without any success.
	When I boot with root=/dev/sda4 instead root=/dev/md1, system is
	more stable (but not enough to be a mail server :-( ).

    With 2.4 kernel and without raid1 (I don't understand  why I
	cannot use my raid1 volumes with 2.4 kernel...), system is
	stable and does not freeze. I have tested hardware with SUNvts
	(from Solaris 9) and it sounds good.

    With the _same_ kernel, an U60-SMP is stable. The difference
	between both kernel are only Sbus versus PCI support _and_
	ESP-SCSI version Symbios support. I suspect a bug in the
	ESP-SCSI support but I don't know how investigate. I cannot
	boot any 2.6.20 with debug option du to a "address not
	aligned" message when it boots.

    Any suggestion ?

    Regards,

    JKB

	I have tried the last 2.6.21-rc4. Same bug.

	What is your U2 configuration ? I have only one U2 and I cannot test on 
this station because it's a mail server :-( In fact, I think it should 
be interesting to know if this trouble come from SMP, ESP or Sbus 
support. It is impossible to build a kernel with debug information (it 
does not boot due to a address not aligned...), but I have tested the 
same kernel on a U1E (with the same ESP chip and two additional 
HappyMeal Ethernet cards on Sbus slots). It perfectly works. Can you try 
a 2.6 on U2 without SMP support ?

	Regards,

	JKB

I have 2 U2's; U2(2x300), U2(2x400).  The SMP doesn't matter, though; U2
with 2.6.x will freeze eventually even if a uniprocessor.  SMP just lets
it fail more quickly.  Problem is believed to be SCSI or Sbus, I think,
but I don't know that anyone is sure.  The kernel people have known
about this for well over a year, but no fix.

For more current information, you might ask squash@gentoo.org or
weeve@gentoo.org --- I haven't tried 2.6 on U2 for a while because no
one has claimed to have a fix for this problem.  (Gentoo spent a lot of
time on this freeze a few months ago, but no satisfaction.  I am sure,
though, that we ruled out SMP as the problem.)

Hi,

I'm running 2.6.20-rc5 on my ultra2 (2x300) for a few weeks now and have not
observed any freezes at all. I attach my config, maybe you can find some 
hint
what causes the problem.

Regards
              Georg

	I have seen your post on gentoo-sparc mailing list. I have made some 
search to find more posts wihtout any success. I'm not sure this trouble 
was known, I haven't seen any post on kernel mailing list.

	I have seen some posts about ESP troubles. For me, all ESP troubles 
were fixed on sparc64.

	I have seen you have tried to build a 2.6 kernel with gcc-3.3 and 3.4. 
I have tried 4.0 and 4.1 with the same result.

That doesn't really mean much. My U2 ran for 45 days on 2.6.12 before locking up 
solid. It was killed by a nightly rsync of the Gentoo portage tree. It had done 
the same sync 44 times previously, but that time took it out. With 2.6.17, it 
hard locked the first time I synced the tree on a new install, but that was a 
full sync instead of just a small subset like with 2.6.12.

Might be private between squash@gentoo.org and davem.  I don't really
remember.  I do know that at one point davem gave us some test kernels
to work with, but they did not fox U2 problem.

Compiler version does not seem to matter.  It does fail for me with 3.3
and 4.x --- I don't recall about 3.4, but I am sure it fails there, too.

Thanks.  I'll compare with mine and see if there is anything obvious.

	I have booted my U2 with 2.4.34.1 kernel. This kernel freezes too (but 
it is very difficult to obtain a freeze : when 2.6 freezes with a 
sendmail queue with only 5000 messages, 2.4 requires 50000 messages to 
freeze).

	Regards,

	JKB

You use the word "people", the plural form, as if there is someone
doing sparc64 kernel maintainence other than me.  That would certainly
be news to me.

This means you have to understand there is _ONE_ person doing all of
sparc64 kernel maintainence, and therefore one person who has to look
at and fix all the bugs, do all the new features, do ports and cleanups
when generic kernel changes occur, etc.

Therefore it should be no surprise that some things slip through the
cracks and are beyond my capacity at times.

You remember incorrectly, that was a fix for Symbios scsi hangs on PCI
based systems, and that bug is definitely fixed now.

The good news is that I can reproduce this problem now on my
Ultra2, I'll try to figure out what's wrong.

Running "dbench 32" a few time is enough to trigger it.

If it is of any use, I have encountered this issue with an Ultra 1 as 
well.  I was using a shell script with an endless loop to untar a 
snapshot of the Gentoo portage tree.

I can provide more details like specific kernel versions tested on the 
Ultra 1 when I get home if that would be useful to anyone (I know I 
haven't tested >=2.6.18 with it off the top of my head).

Ok, I think I might have killed at least the bug I was able to hit.

I make no promises that this will fix the issues everyone else was
seeing, but let's cross our fingers :-)))

Please give the following patch some testing if you can.  And please
be careful, messing with the DMA mapping code can do things like eat
your disk :-)

If all goes well I'll push this bug fix around, and I have a secret
treat for your poor sparc64 SBUS users once we get past this.

Thanks!

    [SPARC64]: Fix SBUS IOMMU allocation code.
    
    There are several IOMMU allocator bugs.  Instead of trying to fix this
    overly complicated code, just mirror the PCI IOMMU arena allocator
    which is very stable and well stress tested.
    
    I tried to make the code as identical as possible so we can switch
    sun4u PCI and SBUS over to a common piece of IOMMU code.  All that
    will be need are two callbacks, one to do a full IOMMU flush and one
    to do a streaming buffer flush.
    
    This patch gets rid of a lot of hangs and mysterious crashes on SBUS
    sparc64 systems, at least for me.

In case problem persist, I own SMP Ultra2 and also digital PC attached dual
input oscilloscope. I can check at electrical signal level whats going on
inside the box if you tell me how.

It's impossible to tell when a bug like this is fixed, of course,
but I've been running U2(2x400)+kernel-2.6.20-r5+<this patch> since 26th
June, and I have not seen a failure.  Now, I have not subjected the
system to any particular stress tests, but before, the daily
updatedb/makewhatis/update-eix cycle plus the daily (gentoo) --sync
operations were enough to kill this system pretty quickly.

So right now, at least, I think you've probably killed the bug.

Regards,
Ferris

Yes, that's why I hate these kinds of bugs.

Thanks for the report.

I did a quick 'ls -l /boot' to get the date, and read it from the wrong
kernel. :(  Correct date is 12 April, 2007.
