bad irq stuff (irqpoll) happening on asus p4p800se after upgrade to 2.6.20-16

Just added the dvdburner again, and it's working fine.
kernel is: 2.6.20-15-386

I did notice that the -16 kernel also had hyperthreading turned on (again).

Is my hardware so obscure?

Thanks for your bug report.

Simon:
Looks like an issue has cropped up with the sata drivers for your motherboard in 2.6.20-16. See Bug #116996 for more details...

The unofficial survey going on here: http://ubuntuforums.org/showthread.php?t=456662&page=20 starting post#195 might yeld some clues, and it would seem there's a lot of folks with Intel ICH4 and ICH5 there.

Some threads have been merged, and the survey is going on in http://ubuntuforums.org/showthread.php?t=456662 starting from http://ubuntuforums.org/showthread.php?t=456662&page=25 post#244 (http://ubuntuforums.org/showpost.php?p=2744328&postcount=244).

This poll is worrying me ... All it proves is a lot of people have ich4 and ich5 chip motherboards .. nothing else.

for the record
00:1f.1 IDE interface: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE Controller (rev 03)

and yes I do have the rename issue

I think its more likley that any chipset that was using libata is affected.

I've not seen any sata or libata (ata_piix) users who haven't had issues.

Andrew:
I have - me! The problem appears to be ICH4/ICH5 users (and if your comment is right ICH6 too). I have an ICH7 and it's still using ata_piix. It would be nice to see a different _ICH6_ owner confirm things over in Bug #116996 so we are clear on exactly which controllers are affected by the ata_piix disabling. While I'm here can you indicate whether you suffer the IRQ timeout/disabled issue too?

The "broken cdrom" issue has been spun off into Bug #117413 .

No my only issue was the renaming of my drives .

The machine is perfectly stable on 2.6.20-16.28 though i did get the ghost cd rom (fstab entry as drive moved from hdc to hdb)

What would you like to prove that my ich6 was affected.??

Its difficult to know which bug to post in as they have been amended (ich4/5) which ain't me

Andrew:
You've done all you can - you've followed up and posted in all the right bugs. We just need a second ICH6 to come forward and say "me too" so that Bug #116996 can be amended (and possibly to split into a new bug because some of the folks in there are suffering from IRQ issues in addition to the "great rename").

I think klmonz in the appended bug-description at the top of bug https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/116996, hits the nail on the head.

Reading through the extensive thread in http://ubuntuforums.org/showthread.php?t=456662, it seems obvious, that Debian bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=419458 describes the core problem with disks, which is the same as *this* bug.

This is FIXED in Debian! I'm sorry, but I have to say that I find it disheartening, that bug https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/116996 is still unconfirmed+undecided, bug https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/117447 is unconfirmed+undecided, and bug https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/117314 is unconfirmed, though recognized as status high.

Please devs! You are probably overburdened, that's understood. BUT.... this bug is wrecking the systems of a hell of a lot of users, and if far worse than the X-oops update you released some time ago. This one is GRAVE, as the Debian bug correctly states. Please please... fix this. Thank you.

nearly a month further, I'm still on 2.6.20-15...

At least the priority is now high :-)

Simon:
A new kernel (2.6.20-16.29) reverting the piix changes was released: http://www.ubuntu.com/usn/usn-470-1 on 08 June 2007. Additionally a new wiki page describing how references to partitions should be UUIDs/labels has recently appeared: https://wiki.ubuntu.com/UsingUUID . Are things any better in 2.6.20-16.29?

I did notice and install a kernel-image update. For some reason I can't find the specific version of the currently installed kernel-image package (I don't want to spend time finding out how). Anyway, the update didn't fix my problem, but it may have been due to not using labels, but /dev/sdb1 directly. I'll check later whether this will fix it.

(rantmode: regardless, though I understand the need for independence of disk order, it does make things more complicated when editing the fstab directly. And the GUI tool is unclear in its use of the term "enable", and didn't work for me (which is why I was editing the table in the first place)

After changing the kernel, fixing the nvidia driver problems I got and finding the right UUID's, I figure it all works now.

Apologies for the implied accusations of tardyness and my lazyness after the .29 update.

I hope the others who posted here also have their problems fixed now.

Simon:
Lars has already posted a response saying the problem is solved at the bottom of Bug #117314 . Andrew is a stalwart of the "great rename" and has already said his particular hardware was OK in https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/116996/comments/75 .

Thanks for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug #117314 and is being marked as such. Please feel free to continue to report any other bugs you may find.
