Hi All,

I am working on a problem where I need to make CPU more than 98% busy.
Is there any open source tool available for it ?

I am currently running 2.4.3-20mdk on my server.

Thanks

Every couple of days I have to login again, and it is quite annoying. Is there anyway to make the login persist for longer?

I need to bring up Linux on mpc5200 based board. the board has uboot as bootloader in it. now i want to replace the uboot with some other custom built bootloader. So to launch linux using custom built bootloader, what are the parameter i need to pass or what are all the initialization i need to carry out before jumping in the location where linux is stored in the primary memory? Or is it just a jump to the location where my Linux bzImage is copied?

First, sooo sorry if this is not the place to report such thing or if somebody else already reported this.

Second, the bug is in the HTML/CSS of the site around the comments: it's written "clas" while it should be "class". An example:

<div class="author">Anonymous</div>

  <div clas="content"><p>
       ^^^^
     --HERE--

That's all.
Thanks for this greate site.

Is the analysis of this article correct?

Am doing my project on Porting u-boot and then the linux kernel on an ARM9 board. The board comes with all these things builtin. But i erased the kernel from the flash (on minicom), and then tried to copy it onto the flash by serail line.
Somehow i got an error. From then on am unable to access the board through the minicom. When i open the minicom it just gets struck after displaying www.kwikbyte.com.... which is the official web site of the makers of the board. Anyone please help me out.

Kirk Murrin of Linux Guru Consulting has published a clever looking demo hack that adds a web interface to mconfig. The hack aims to let users configure and build Linux kernels remotely, access kernel and driver documentation, and even use browser forms to add and edit source files.
