maybe I missed something and very sorry if it's the case but I'm at 1b4f70ca7103 and
| Code: | eb64@drama:~/pkg/kernel26zen/src$grep Kolivas include/linux/sched.h
printk(KERN_INFO"BFS CPU scheduler v0.323 by Con Kolivas.\n"); |
ck provides incremental patches so that should not be too hard to get latest BFS but is there any reason why I shouldn't do it?
thanks. |

+1 noticed that as well.
TOI does seem to sometimes fail and just keeps writing caches or trying to freeze system with no errors forever. |

switching the clocksource from hpet to tsc or acpi_pm might fix it for you:
put
or
| Code: | | clocksource=acpi_pm |
to the line where your kernel is called at grub.conf / menu.lst or lilo.conf
that seems to have fixed it for me under 2.6.35+ and 2.6.36-rc*
cheers ! |
Is one of these preferable under ordinary circumstances? I can't find too much info on these. My box always seems to naturally prefer tsc unless I override it. I think it chooses tsc when dynamic frequency scaling is enabled. |

acpi_pm is reliable under all circumstances but is much slower, incurring much greater overhead which is why it's not used by default. However if your other time source is unstable, there is not much you can do but wear the extra overhead. |

How about the other one? "HPET" sounds "Highly Precise!", which I hear is a good thing to look for in a "Timer" of "Events".

and

you should prefer acpi_pm, this should be especially true on laptops |
Doesn't look like I'm getting those (even with ondemand cpufreq, linux-PHC patches, intel idle driver, etc etc)
Some relevant looking lines:
| Code: | ...

No results for "unstable"

Interesting. What kind of hardware?
Currently used should be in /sys. Try:
| Code: | | for i in $(find /sys -type f -name '*clocksource'); do echo -e "$(basename ${i}):\n$(cat ${i})"; done |

This is a laptop (T61). | Code: | ~> for i in $(find /sys -type f -name '*clocksource'); do echo -e "$(basename ${i}):\n$(cat ${i})"; done
current_clocksource:

Oh, I am not using zen-sources. I was using it until about two days ago. In either case, my system has always used hpet automatically.

Same results, running 2.5.35-zen2

I pulled current zen-stable master and built a new kernel on my XPS M1330. Low and behold, it actually boots this time. 
But, no network. Ive tried everything I could think of; this is what I get.

I switched a laptop and desktop over to Zen this past week. So far so good.
Thanks to those who put this kernel together.

Turns out, there is more to it than some bad driver for my ethernet. I figured out my wireless was not working either.
Found out the Sonics Silicon Backplane driver was complaining about unknown SPROM version. Some Google-fu provided me with a way to find the sprom version it was getting, which was interesting.

You can see when compared to 33-zen3 something looks a bit off. Straight 1's?
Heres boot log for .33-zen3

And .35-zen3+

| Have all of the 2.6.36 i/o interactivity patches been backported to 2.6.35-zen3 or should I stick with vanilla 2.6.36-rcX for now? I want to try this new version of BFS, but don't want to lose the i/o fixes. |

Any indication on when Zen-3 will be in portage?
