genstorm: It's caused by swap prefetch. But now it's fixed.
unK: yeah, happening here too. We think this happens if swap prefetch is enabled. |

Does it affect both master and master-devel?
Btw, it is possible to switch from latest revision to e.g v2.6.24-zen2?

Thank you, I tried some combinations with git checkout, but apparently I didn't try the simplest one ;p

@kernelOfTruth
BTW, I haven't forgotten about the config problem. ^^; It seems to be a bug in the config system. When I have the time, I'll investigate further, patch, and push upstream. For now, I'm really sorry that it fails for you. :/ The best workaround is to use one of the graphical configs or to throw your options in to the .config in a text editor. |

My 2.6.24-zen2 does not poweroff properly. It just hangs on the very last part where it normally should poweroff the machine.
This is my .config. I have already tried booting with acpi=force but that didn't change anything.
Any ideas? Rebooting works fine. |

Remove CONFIG_PREEMPT_RCU=y.

After recloning my repo yesterday I compiled 2.6.25-rc3-zen0-03138-g562d6ce and proceeded to emerge ati-drivers-8.433. Kernel compiled fine(they always do) but ati-drivers died with this message:

I am using Classic RCU, I learned from last time. Did I miss something in .25 that changed radically?
Thanks in advance for any tips.

I had to remove the first function from the C1E patch to get it to work, as well as disable aufs, unionfs, chunkfs, madwifi, and a ralink driver, but 2.6.25-rc3-zen0 compiles and runs cleanly. With it, I am able to boot my HP laptop dv9205us without using noapic or nolapic, or both, which is a monumental achievement. It is also wonderful that my wireless card is native now.
RMH, Waninkoko, devs, YOU ROCK!

swap_prefetch bug in master-devel is being worked on (by tomorrow it should be completely fixed). There is also new alsa from mm in master-devel.
Also, i just pushed btrfs 0.13 to master.

Waninkoko, you did an amazing work, but i have to agree: 2.6.23-kamikaze5 is much more mature especially for my notebook than zen is. It uses 2 watts less power, reboots/halts stable and hibernate/suspend works more stable too. Indeed I use this last kamikaze with updatet alsa and iwl-wifi.
Nevertheless i will test every new release! Thank you very much for your efforts!
Best regards

Try disabling preempt rcu. |
Hi Waninkoko, i've tried this but it did not change anything. Latest kernel, that halts and hibernates properly, was 2.6.24-rc7-zen2 (with preempt rcu). Since then i can't power off the laptop, neither with or without preempt rcu. I have an completely intel based laptop.
Thanks for your efforts! and best regards

What's the C1E's patch ?
Is there a way from linux to set the CPU ratio without speedstep activated as in windows ?
(I ask for core duo 2 CPU) |

The C1E patch disables a function in the AMD chips that causes lapic to incorrectly report that it is broken and disabled. It doesn't effect Intel users.

Hi folks.
Perhaps somebody can sched some light on below..
Can somebody explain what the difference between 2.6.24-zen4 and 2.6.24-zen-rt3.
Are these different revisions? What for? How can I get access to zen-rt3?
From what I recall Ingo offers a "Complete Preemption" mode and threaded SOFT-/HardIRQs.
Would be nice to have these in standard ZEN, if not already included. If these are somehow redundant
to other ZEN specific parameters forget that comment.

Hi kls,
zen-rt is the branch with your mentioned features (soft- & hardirq)
if you're already cloned zen-sources checking out 2.6.24-zen-rt3 should suffice
Cheers
