The link I posted had nothing to do with INTEL_IDLE, it was CPU_IDLE. They are not the same thing.

| False. The only difference between the two config files he posted is CONFIG_INTEL_IDLE. See for yourself. |

Suit yourself, good luck getting your problem fixed.

Let's get this post back on topic here...
Does anyone know the source of the slowdown in 2.6.35 or how to mitigate it? Gigantic locks when booting sometimes? Slow typing? Usually if I power on and off a few times it works eventually, but still slower than 2.6.34. |

I am also seeing hugely varying boot times. On 2.6.34 I get 20 to 30s boot on my WDC 2TB green drive as boot with my i7 920 clocked at 3.0GHz to 3.1GHz but in 2.6.35+ I get 65s to 300s boot times and it does not appear that the same kernel takes the same time to boot each time I boot the system.

I have had this problem with git-sources, gentoo-sources and zen-sources. With and without power management on in the bios or in the kernel. I have tried many options and I have generated dozens of kernels so far to test this..

I didn't look at the links, I went by the text above the links and he specifically said CPU_IDLE,
maybe the links he posted were wrong and maybe he really meant INTEL_IDLE.
The symptoms that he mentioned, seemed awfully close to yours and others though,
and I simply mentioned what I found.
Later dude.

Do you have a plan currently? I'm at a loss for where to look at this point. |

I just tried the sysrescuecd beta (containing 2.6.35) kernel and though that fixed the issue so I installed the kernel (and modules) from the usbstick to my system and the boot was just as slow as before but typing seemed fine. Besides slow boot I do have 1 way to verify the problem is happening on a kernel. In the console open less and press down till you get the system beep. On a system with this problem sometimes the beep will hold pitch for 10+ seconds. On a normal system this does not happen.

I am going to take a break from this for a few hours. With the sysrescuecd kernel doing this I am not sure where to begin. I wonder if the beta 10.10 ubuntu livecd uses 2.6.35.
I could also try bisecting the git kernel to find the change that caused this slowness but that seems to be a lot of work.

I installed ubuntu 10.10 beta (containing a 2.6.35 kernel) on my i7 system using a brand new WDC 1TB black drive. The install took 90 to 120 minutes and had a very unresponsive gui (almost unusable). After install I booted into ubuntu and all the slowness exists in ubuntu. The boot took over 170s. The gui was very slow and the console had the same sticking bell.

@drescherjm
Curiously, I'm able to get it decently fast if I power it off when it starts to go slow and try again, and do this over a few times. Usually it becomes fast enough by the third or forth boot. But still, the overall performance, even when I get it to boot right, is still slower than .34.
What hardware do you have? Here's my lspci and /proc/cpuinfo:

I turned off kernel premption under 2.6.35-zen and still have the slowness..
| Code: | jmd1 ~ # uname -a
Linux jmd1 2.6.35-zen2-sleep #2 ZEN SMP Sun Sep 5 10:29:59 EDT 2010 x86_64 Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux |
sleep is a local string that I added.
| Code: | [ 254.919334] ip_tables: (C) 2000-2006 Netfilter Core Team
[ 255.087188] nf_conntrack version 0.5.0 (16384 buckets, 65536 max)
[ 255.087348] CONFIG_NF_CT_ACCT is deprecated and will be removed soon. Please use
[ 255.087350] nf_conntrack.acct=1 kernel parameter, acct=1 nf_conntrack module option or
[ 255.087352] sysctl net.netfilter.nf_conntrack_acct=1 to enable it.
[ 258.370258] NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory
[ 258.370387] NFSD: starting 90-second grace period |
The second line normally happens at 25 to 28s on a 2.6.34 kernel not 255..
Hmm. I do have intel idle on this kernel. I know it was disabled in other 2.6.35 kernels but I will try disabling that:
| Code: | jmd1 ~ # zgrep IDLE /proc/config.gz
CONFIG_ARCH_HAS_CPU_IDLE_WAIT=y
CONFIG_ARCH_HAS_DEFAULT_IDLE=y
CONFIG_CPU_IDLE=y
CONFIG_CPU_IDLE_GOV_LADDER=y
CONFIG_INTEL_IDLE=m
CONFIG_I7300_IDLE_IOAT_CHANNEL=y
CONFIG_I7300_IDLE=m |
Here is what I had in 2.6.35-gentoo-r5
| Code: | jmd1 linux-2.6.35-gentoo-r5 # grep IDLE .config
CONFIG_ARCH_HAS_CPU_IDLE_WAIT=y
CONFIG_ARCH_HAS_DEFAULT_IDLE=y
CONFIG_CPU_IDLE=y
CONFIG_CPU_IDLE_GOV_LADDER=y
CONFIG_CPU_IDLE_GOV_MENU=y
# CONFIG_INTEL_IDLE is not set
# CONFIG_I7300_IDLE is not set |
And here is 2.6.34-gentoo-r8
| Code: | jmd1 linux-2.6.34-gentoo-r8 # grep IDLE .config
CONFIG_ARCH_HAS_CPU_IDLE_WAIT=y
CONFIG_ARCH_HAS_DEFAULT_IDLE=y
CONFIG_CPU_IDLE=y
CONFIG_CPU_IDLE_GOV_LADDER=y
CONFIG_I7300_IDLE_IOAT_CHANNEL=y
CONFIG_I7300_IDLE=m |

This seems related to network or something.
2.6.34 will shutdown fine BUT 2.6.35 openRC ends up waiting for EVERY net service to terminate, but they don't so 2min shutdown and init ends up killing the processes

Disabling intel_idle in 2.6.35-zen-2 did not help. Again the following lines are at 25 to 28s on 2.6.34.

[ 260.313448] sysctl net.netfilter.nf_conntrack_acct=1 to enable it.

I have not been patient enough to watch shutdowns on 2.6.35. I do know that they are very slow however. Most of my testing as been via ssh and waiting for the reboot sometimes takes 5 minutes..
I am using openrc.

I just enabled kernel preemption on vanilla, and the problem persists. Does zen preemption fix the problem or something? |

No. It did not work.
I am done for now with my attempts to run 2.6.35 on my i7 machine. disabling CPU_IDLE (and all ACPI power management) caused a hard lockup 1.04 seconds in. Just after the calculation of the 8 core bogomips.

TEMPORARY WORK AROUND!
Disabling "CPU Frequency scaling" in the power management menu seems to have fixed the problem.
So somewhere in here lies the problem... |

At least partially... There's still some slowness, but overall it seems improved.
Can someone else try this and report back? |

I guess the Linux scaling is a bit too agressive

I did. That did not help. I also tried kernels from other distributions, all had the slowness.
