Hi,

Hi All :

We do power cycling test over our dual port 3G/6G drive test over LSI 3G 1068E/ 6G 2008 Controller. We sometime found the port get swapped during the power cycling. It happened more often in 3G SAS controller than 6G controller.
For example:
In the beginning before power off,
phy 0, sas_addr 0x50014ee30005078e were associated with sda and sg2
but after power on.

Hey I was going through Broadcom Tigon 3 drivers code and I see that APE memory is mapped using pic_ioremap_bar(pdev,BAR_2).

I couldn't any information in the broadcom datasheet about APE memory. What is an APE memory and what exactly it is used for?

my hp proliant DL185 server doesn't boot up as expected .

i've managed to capture the msgs & traces dumped to console. See below

Hi,

I am using the following kernel module to intercept some syscalls. I have got sys_call_table address from the /boot/System.map.x.x. The module works file on Ubuntu 7.10 (2.6.24) but gets killed upon insmod in Ubuntu 10.04 and Fedora 12 (2.6.32) with error "Kernel paging request error address c0xxxxx [which is, based on System.map, an address in sys_call_table]".

Hello,

I have a old SuSe Linux 9.3 distribution with a 2.6.11.4-21 Suse Kernel.
Now i have new Hardware and will the old system run on this new Hardware, but some new Hardware
is not working (Network, PCI, Graphic an so on). And i need the old System (very important).

So i compiled an new Suse kernel (2.6.31 from Suse 11.2) on the old Suse 9.3 in the new Hardware System.

I want to write a loop that sucks up all the 2mb slugs of memory I can get in the kernel. However, I want to leave "some" free space (say 20% of the machine's total phys mem). So, how can I do that? I have a loop now something like as an experiment to get all the mem I can and then release enough for the system to continue running but the kernel hangs:

for( i = 0; i < MAX_SLUGS; ++i )
{

Where is implemented in the kernel linux the Limited Transmit Algorithm? It is explained in rfc 3042.. I have not found it in the tcp_input.c file...

I'm using RHEL 5.4 with the kernel 2.6.18-164.Can I introduce the CFS into the kernel by adding a patch,or should I create the patch myself?
Is there any available patch for this kernel?

Hello, i am dealing with studiing kernel module. As example i am using block device from lwn
http://lwn.net/Articles/58719/

and so far so good, but i am trying to create simple network disk (just for test, ...)

I found this article.

Is there any way to know the L2 cache size from examinging to boot log. Here is my boot log

I am trying to create a socket server in user space and a client in kernel space and send big messages (a little over 64kbytes) between them.

I used an kernel socket programming examplefrom this link - http://www.linuxjournal.com/article/7660 for the kernel client side.

Hi,

I am experimenting netlink socket for kernel space to user space communication in linux 2.6.32 kernel.

My intension is to perform,

kernel space --------------> user space
kernel space <------------- user space

i have few questions,

1) how to determine the pid of the userspace process, if kernel is going to initiate the communication by sending the data.
