About to install and test, hopefully the fixed the preempt / XFS problem. I will post back my results and let you know what happens, perhaps I will see no more exited with preempt_count ;)

Well so far I still get the same error that others were recieving while compiling, something to do with smp. I will fix this problem, install the kernel, reboot, and post steps later.

Where is the source for the latest kernel source announced by Daniel Robbins? I could not find it in the Gentoo mirror (www.ibiblio.org). I want to download the source somewhere else instead of "emerge ...." from my machine since my machine connnection is thru slow modem.

If you don't use XFS you should turn it's support in the kernel of.
Somehow it's olways on, even if you use your own config file.

I got the ACPI error also.

I corrected this by selecting "APM" and "ACPI" in the config.

Note that you don't need to select everything (or anything) under either one of these (although I suggest you select the APM one about turning your PC off so it turns off when you halt). You just have to have the "support" for them.

hope that makes sense...

Use the --fetchonly (-f) argument?

Yep I did the same compiled and still get the preempt errors when booting the kernel and when an app exits. That problem and my konqueror causing a hard lock-up withing 5 minutes or less while using it in online browsing mode is a drag.

I know it's not kernel related but it seems I am one of the few left having these konq problems. I just re-installed from stage one and emerged system, fluxbox, then kde so I have all the newest packages. It really is a damn shame that I can't use konqueror, it is beautiful now with the fonts being anti-aliased so nicely :(

i turned XFS off and preempt on and mine compiles fine... r3 was fine for that matter... XFS is a wacked patch if you don't need it don't use it. I also suggest totally unemergeing the old kernel dirs and deleting them (/usr/src/linux...)(/lib/modules/linux...) then you emerge the new kernel... with this method i have been able to compile the new kernel... reboot... then in the new kernel compile my modules (NVdriver, emu10k1) reboot... and the system is back to normal...

I have given up on XFS and am in the process of switching to ext3, it just seems XFS is not worth the headache. Besides several benchmarks performed by various sources have shown ReiserFS and ext3 to be valid, capable, well performing filesytem that out perform XFS in most ways....Each filesystem has a use and IMO for regular desktop usage ext3 or ReiserFS seems the way to go :)

I tried installing r4 today, and all I could get was a kernel panic on boot.

I'm getting more and more disappointed with Gentoo. It seems that every time I update my kernel, I end up having dozens of problems, which I never had on other distros when updating a kernel.

here's my 2 cents..
r3 was a hell, didn't compile at all on 2 diff machines until i figured out that one machine didn't like Low latency and Preempt on at the same time..

Once I figured that out r4 was finished, and am happily using it now on both machines, that's with XFS/usb/scsi/v4l/low latency and Preempt..

And yes, I get the messages ls(67) exited with preempt_count 14..
I'd think myself these are debug messages enabled in the Preempt source..

oh well.. r4 works, and kernel debug messages headed to /dev/null
problem solved ;)

Sib your assumption is incorrect, those messages mean preempt is failing to function. If all things were going well you would see nothing, but if you did get a preempt kernel message the count would have to equal 0 for preempt to be functioning properly.

Update on my issue:

I changed over to ext3 and all is well with the preempt and low latency options.

Just a quick one autobot. How did you migrate to ext3. I am currently running xfs and thinking about doing the same. Did you have to rebuild or is there an easier way. Thanks in advance.

I gzipped my entire / directory, cp'd it to a safe place, made a new partition, zero'd it out, mke2fs -j /dev/hdaX, un-gzip'd it back to / with time to spare lol.

I was using r3-gentoo and couldn't use my drivers so reinstalled to get vanilla and in the process also got r4. Now i can't boot.

Great! with r4 it's the first time I get no more ACPI errors during booting, also the sound works now (I guess due to ACPI and interrupt selection) without any problems :D . Just acpid won't start anymore :( .. but that's for the bug-forum

I'm also seeing the
Code:
exited with preempt_count
messages.

After having a search round, I found a message from Richard Love saying that SGI's XFS buggers up the preemptive stuff. Since I'm running XFS, I wondered if this was the problem. Anyone else in the same boat?

Here's how I got out...

PostPosted: Sat May 11, 2002 2:40 pm    Post subject: I ditched my XFS months ago because of these and similar.. Reply with quote

Issues, issues. XFS sucks...

Anyhow, to get off of it, this is what I did.
I had a second hard drive, so I went:

login: root
password: *********

/root# cd /
# mke2fs -j /dev/hdc1 # make new ext3 partition on second hard drive
# mount /dev/hdc1 /mnt # mount it
# find / -mount -print | cpio -pdm / # fine all files on your current partition and cpio them over.

The cpio part is important because you want to keep your permissions intact.. If you do a regular copy, be sure to use -Rfp flags to keep permissions intact.

Good luck!
