Ho ho ho.. Linux 2.6.15-rc7

Now, most of you are probably going to be totally bored out of your minds on Christmas day, and here's the perfect distraction. Test 2.6.15-rc7. All the stores will be closed, and there's really nothing better to do in between meals.

A number of mostly one-liners. The biggest ones are probably some s390 qeth updates and some ipv6 fixes, the rest is just a number of small fixes. The shortlog gives a pretty good picture of what's going on. I suspect the forcedeth fix is the one most likely to affect any reasonable number of people, although the more relaxed usb suspend probably makes a big difference.

Please do give it a try, and if you have any issues/regressions, send out a note (even if you sent one earlier) so that we don't forget about it.

Thanks,

Linus

Bah, Hum(de)bug!

For first time I tried running firewall box on 2.6 series with 15-rc7, worked first time: http://bugsplatter.mine.nu/test/boxen/deltree/, an old pentium/mmx with f00f bug.

Only copied /etc/modules.conf to /etc/modprobe.conf, iptables and all else (NFS, ADSL, Samba) working without change to .conf files.

Thanks,
Grant.

Hey that is a good ASCII site! Very useful for debugging one's issues.

/me will bocome a copycat if only /me had a bit more time.

Good idea, thank you. I love the simplicity of it.

Hello,

Just booted my own 2.6.15-rc7 on a machine based on ASUS A8V-Deluxe with AMD Athlon 3800+, and it is really working fine ! I also now have smartd working using -d ata for the SATA disk...

Still have to check ATI proprietary driver for X.org, but vanilla is great !

Thx,
Paul

Hi Linus,
I've visiting at my parents house and gave 2.6.15-rc7 a try on my
dad's machine. This machine is his normal desktop box which I administer remotely, as well as a MythTV server. The new kernel built and booted fine. I then built the NVidia stuff. However when I tried to build the ivtv driver from portage it failed:

Most probably this is stuff the Gentoo devs will clean up when the
real kernel comes out but I *think* you were asking for this sort of info so I'm posting it back.

Cheers to all,
Mark

There's nothing the kernel developers can do about regressions in out of tree modules - there is no stable kernel module API so the authors of that module will have to fix it.

Any idea why the IVTV module has not been submitted for mainline?

Lee

Lee, et all,
Yes, I understood ivtv wasn't part of the kernel, and I did
consider trying something newer, but that meant testing that this new ivtv didn't cause other problems which I didn't have time for as I'm leaving tomorrow morning for home. Testing ivtv within MythTV is a long involved process (literally hours and hours really) and I didn't want to leave my folks without their beloved TV recording system if something went wrong. I'll test the new kernel on my machines at home, including with ivtv, and then I'll update them when I know it works for me.

None the less, and maybe as a non-developer I'm seeing this wrong,
but when a new kernel causes some drive to say a symbol isn't available, as a user type I have no way of knowing if the symbol was dropped on purpose or something got left out.

I'm glad it's considered a non-issue.

Best regards and Happy upcoming New Years,
Mark

Little by little, ivtv is being merged into V4L. There is a lot of reorganization that is taking place, and it is not a very fast process.

As of 2.6.15-rc1, many of the modules from ivtv were merged into the kernel through V4L. Recently, there was another ivtv fork discovered, called paken. (for better details, see ivtv mailing list archives) The ivtv guys are currently working on cleaning up the main ivtv module, and merging in the code from the paken repo. When all is ready, it will all be merged into v4l, and eventually the kernel.

Cheers,

Michael Krufky

No idea. I even asked the IVTV developers mailing list some time ago trying to get them to include it in mainline, but they did not want to for some odd reason I could not work out.

Maybe someone else can kick them a little harder. :-)

James

Hehe... Please see the earlier messages in this thread... It is a plan-in-motion. Maybe for 2.6.17 or 2.6.18. ...depending on some other factors...

[ivtv-0.4.0 not compiling on 2.6.15rc]

Hi Mark,
the ChangeLog of ivtv-0.4.1 says:
[...]
- support 2.6.15 kernel changes.
[...]

Em Seg, 2005-12-26 às 10:02 -0800, Mark Knecht escreveu:

IVTV is not part of kernel. You should try instead ivtv-0.5 stuff
(there are several duplicated modules between kernel and ivtv-0.4 that were removed on 0.5 as part of a strategy of having it included on some newer kernel version - maybe 2.6.17 or 2.6.18).

Cheers,
Mauro

Mark-

You don't have to worry about this... Since ivtv is an out-of-tree kernel module, and 2.6.15 is not released to mainline yet, so you cant expect the distros to make their external driver packages compatable.

Anyhow, I believe that ivtv 0.5.x is meant to be built against 2.6.15 ... We have been merging some of the modules from ivtv into v4l, and some of those modules have already made it into 2.6.15. I think you will run into module collisions using ivtv 0.4.x with kernel 2.6.15, but i'm not sure about that. Please see the ivtv mailing list / web site for more information about this, and how to get it to work with your kernel.

Eventually, the ivtv driver will entirely be merged into v4l (and the kernel), and things will be much easier. Until then, you should try the new 0.5.x version of ivtv with Kernel 2.6.15

Cheers,

-Michael

Hmm. Somebody broke UML compile for my config again...

Below is a patch by Andi Kleen from kernel Bugzilla #5758 fixing a post-2.6.14 regression.

Reject SRAT tables that don't cover all memory

Broken BIOS on Iwill reports these and it causes the bootmem allocator to crash. Add a sanity check if all the PXMs in the SRAT table cover all memory as reported by e820.

This patch fixes kernel Bugzilla #5758.

WTF are you submitting my patches? Please don't do this - I am perfectly capable to do this on my own when the time is ripe for them. For this patch that's post 2.6.15 and after more testing.

-Andi

According to the bug logs this is a regression in 2.6.15-rc, and it's not good if 2.6.15 will not boot on some machines where 2.6.14 did.

The risk at this stage of breaking more than fixing is too high.

Especially since it's only one relatively obscure machine with totally broken BIOS. And a workaround exists.

Please leave the decision of what patches are release critical and what not for x86-64 to me. Thanks.

If it worked in 2.6.14 then only by extreme luck and probably also ran into problems later. The BIOS in this case is terminally broken.

So I wouldn't consider this a real regression.

-Andi

Unless I misread the Bugzilla bug, the submitter was extremely lucky in 2.6.14 making it a regression for him.

But discussing this point won't buy us much.

Would you veto against a section "known regressions" in the final 2.6.15 announcement listing this issue with a link to the Bugzilla bug?

Yes for this case. The original was likely so fragile that it might break only with minor changes in the hardware configuration.

In general listing known regressions is a good idea though.

It might be a good idea to give them different priorities though - e.g. a broken BIOS with a missing workaround is less priority than a pure Linux bug.

-Andi

I'm currently struggling with a probable case of broken BIOS without workaround, is there a central repository of known simular problems? Is there a way to pinpoint such problems to prevent people from tossing these into bugzilla?

[ . . . ]

No, this bug is not present in Linus's tree.
