Hi
I have a system that consists of 14 processoes .Under high load one processor shows 100% usage and rest show normal behaviour.Driver is NAPI compliant.So is it a driver issue or scheduler issue?. Kernel is 2.6. The output of "top" commands show that the cpu that is 100% consumed is running ksoftirqd and it is 0% idle and 100% SI.

Interrupts are evenly distributed over the system

HI everyone,

I tried to install btrfs on my root filesystem (/), this is what I did :

install debian with :
/boot (ext2) (for grub),
/ (ext3),
swap,
grub on MBR.

compile the 2.6.31-rc4 from kernel.org with btrfs support
test the new kernel by rebooting (worked fine)
install btrfs-tools from debian sid repository (0.19-2)

boot on a ubuntu 9.04 live cd

Issue:

If I play the wav file using "aplay", underrun error occurs.

I am suspecting the issue in driver or in kernel code.

I am using the following setup:

a) Application and Library:
aplay in alsa-utils-1.0.16 and alsa-lib-1.0.16.
b) Platform: imx27
c) kernel: linux-2.6.25

Hardware & Software parameters for aplay:

I am using Debian Lenny with 2.6.30 kernel on my Intel Atom Poulsbo chipset computer and I get the following messages in my dmesg when I start the X server:


[ 22.760737] mtrr: type mismatch for 3ffc0000,10000 old: write-back new: write-combining
[ 22.760805] mtrr: type mismatch for 3ff80000,40000 old: write-back new: write-combining

Hello,
could anyone save me from recompiling the whole kernel and rebooting, if I need tun.ko?

I want to use a vanilla kernel on my embedded x86 machine.
I have 3 options:
1. Run Dan kegel's last script: it uses 2.6.15.4
2. Use the LFS 6.4: It uses 2.6.27.4
3. Use the last version in kernel.org: 2.6.30.1, But with what tools version ?

can anyone explain the metadata btree structure of btrfs ??

HI

I want know can I give priority between serial ports, in case if three serial ports receive data at same interval (1 second) with different lengths of data say 64 bytes (512 bits), 16 bytes (128 bits) and 4 bytes (32 bits).
Is it required to give priority considering data is supposed to be received at same interval? Please enlighten me...

Hii

Hi,

I would like to know if "Command could be aborted by ahci driver just after filling the command FIS (H2D command FIS is filled using ahci_qc_prep), how this could be reported back to upper layers gracefully".

Will highly appreciate any clue or suggestion on this.

Regards,
Stan
