hm, i think these were all fixed a long time ago, via:

 f6d87f4: genirq: keep affinities set from userspace across free/request_irq()
 612e368: genirq: fix the affinity setting in setup_irq
 6c2e940: x86: apic honour irq affinity which was set in early boot

Kumar, could you please check v2.6.28-rc9 to see whether all issues are 
fixed?

not really a regression but a long-standing inconvenience/bug of the debug 
symbols of relocatable kernels. (ever since relocatable kernels were added 
in '06 or so.) Nevertheless we queued up a revert of the defconfig change 
for .29, to not expose it in the defconfig:

 f269b07: x86: revert CONFIG_RELOCATABLE=y defconfig change

so i think it can be taken off the regressions list.

it's not a regression nor a hideously critical issue.

Yes, I'm still seeing this on .28 and even on .29-rc1.
I checked again and couldn't trigger the regression on a .27 kernel (at 
least with my hardware and config).
So, I'm fairly confident that it's a regression, not just a bug that's 
always been there.

I'm still seeing this on .29-rc5, and I think that my bug #12263 is a 
duplicate of bug #12609,
or more correctly it's a duplicate of mine because I reported first.

It seems like the bug has been fixed in tip/master for some time now.
Below is the diff of origin and tip from when I tested.

This one, done on Jan 10, more than a month ago:

  f1d26da: Revert "libata: Add 32bit PIO support"

When a commit causes trouble in -tip qa i immediately revert it in 95% 
of the cases, no questions asked. Especially if it's related to 
persistent storage.

OK, thanks.

We seem to have a working fix patch for this issue in bug #12609.

    Wait, if this is indeed post-2.6.27 regression, it couldn't possibly have 
been caused by that patch which got merged during 2.6.29-rc1 timeframe. 
Something's up with this bug...

SATA uses the SCSI layer, right? It could then perhaps be these bits in 
tip:out-of-tree:

 813104e: Revert "[SCSI] simplify scsi_io_completion()"
 84db545: Revert "[SCSI] Fix uninitialized variable error in scsi_io_completion"
 0eb6038: Revert "[SCSI] Fix error handling for DIF/DIX"
 3cd94dd: Revert "[SCSI] scsi_lib: don't decrement busy counters when inserting commands"
 c27aed5: Revert "[SCSI] scsi_lib: fix DID_RESET status problems"

i needed these to keep an aic7xxx box from crashing. This regression got 
introduced at around 2.6.28-rc1, so it fits the timeframe.

    Also, it's been reported for a hard disk while regression in bug 12609 
only hits the ATAPI devices. I think that bug 12263 needs to be reopened.

    After referring to the SCSI command codes "cdb 0x1e" means ALLOW MEDIUM 
REMOVAL command -- which could hardly be addressed to an usual hard disk. So, 
it looks like we had a case of the confused bug report which has a lot of info 
on the hard disk while errors were most probably happening with a CD/DVD 
drive. :-)

Yes, I originally thought it was my hard disk because the kernel logs showed ata2.

But, Tejun Heo figured out it was my DVD drive (ATAPI) that was on the ata2 link.

(see http://marc.info/?l=linux-kernel&m=122993014109646&w=2)

I tried to bisect it, but around .28-rc1 I began to get numerous compile errors, so couldn't continue.

I also tried patches that Tejun sent me, but non of them worked, it just slightly change the error message.

So, yes this is a regression that was introduced in the .28 merge window, and I still think that bug #12609 is a duplicate of my bug.

I don't see this bug on tip/master and this is the diff of origin and tip at the time I tested.

    If 12609 is truly a post-2.6.28 regression and 12263 is post-2.6.27 
regresssion, this just cannot be.

Maybe the reporter of #12609 didn't notice/test kernels 28-rc1 to 28. Or 
maybe the difference in hardware is
the issue, but the bug is still the same. Don't know.

Sorry Justin, you must be confused: as Sergei says,
#12609 and #12263 can only be different.

I was one of the reporters of #12609, and I do know it's a post-2.6.28
regression (and Larry said so too), and one fix (not the preferred fix)
is to revert the ata_bmdma32_port_ops from 2.6.29-rc, and the preferred
fix is to improve the ata_sff_data_xfer32() introduced in 2.6.29-rc1.

2.6.28 does not contain any ata_bmdma32_port_ops, nor ata_sff_data_xfer32(),
not did 2.6.28-rc1 contain them.  So it is impossible for the reversion of
the patch that introduced them to fix any problem on 2.6.28.

I'm quite prepared to believe that your #12263 manifests similarly to
#12609, and that a tip tree which contains a fix for #12609 contains
a fix for #12263; but please, those bugs are not the same, and they
don't have the same fix.

Well, like I said: "[I] Don't know". I'm not a kernel developer (or even 
any developer... yet).
I'm just someone that tests the -rc kernels to see if there's any 
problems with my hardware.
I try to report any regressions to lkml, and hopefully help the developers.

To me, who has no knowledge of all these low level issues, the following 
error messages
look strikingly similar with a quick glance.

So, will the patch for 12609 fix my issue also, or does there need to be 
another patch?

   Note the different value of the status, error and interrupt reason 
registers: 51/20:03 vs 50/00:01. The former means (unexpected?) status 
phase interrupt with error indication and the sense key NOT READY, the 
latter means (unexpected?) command phase interrupt with no error. IIUC, 
the former happens once the 'sr' driver first sends the TEST UNIT READY 
command while probing the CD/DVD drive, the latter seems to be a result 
of some polling process (originated from userland) -- I'm not seeing 
ALLOW_MEDIUM_REMOVAL anywhere in this driver. So they only look similar, 
I think...

And that is why I'm a tester and you're a developer ;) Thanks for the 
info! Next time I'll look closer
and maybe know what I'm actually looking at.

So then, #12263 should be reopened and marked as not a duplicate.
Anyways, if tip/master gets merged how it is now then my bug should be 
fixed.
