Short Description of Problem: Linux 2.6.21.3 does not run properly with 8GB of ram on the Intel 965WH motherboard. Long Description of Problem: When I use 8GB of memory on my x86_64 system, CPU-bound processes are VERY slow, up to 36x slower than usual. My temporary fix is force Linux to only use 4GB of memory, I am currently using mem=4096M. I ran memtest86 and the memory is fine, not a single error. I tried the following to mem= 1024, 2048 4096 and blank "" to let the kernel use all 8GB of m...

Hi, Recently i switched from old ide interface to new libata (pata) interface. With old drivers all's be ok.

I'm pleased to announce the availability of version 6 of the syslet subsystem. Ingo and I agreed that I'll handle syslet releases while he's busy with CFS.

> You should pick up the kevent work :) Yeah, but I have lots of competing thoughts about this. For the time being I'm focusing on simplifying the mechanisms that support the sys_io_*() interface so I never ever have to debug fs/aio.c (also known as chewing glass to those of us with the scars) again. That said, I'll gladly work closely with developers who are seriously considering putting some next gen interface to the test. That todo item about producing documentation and distro kernels ...

.. so don't keep us in suspense. Do you have any numbers for anything (like Oracle, to pick a random thing out of thin air ;) that might actually indicate whether this actually works or not? Or is it just so experimental that no real program that uses aio can actually work yet? Linus -

Hello, this patch is against current input tree. Xbox360 pad has four leds, which forms a circle. Unfortunately the leds itself are not independent, and we can't control them directle, but rather through sending commands which have predefined meaning (like turn first on, others off) This patch allows us to send these commands via leds subsystem. Commands itself are described here: http://www.free60.org/wiki/Gamepad. Led subsystem allows us to set brightness, but there is nothing like brightn...

Permissions management of the LEDs is outside the scope of kernel. If you need users to have access to them, change the permissions in It leaves it up to the driver concerned. In your case it makes sense so counting is fine. Don't put the colon in though, just have it as xpad0 etc. as the name. Anything after the first colon is defined as an optional colour (see Documentation/leds-class.txt). Richard -

That failure mode is pretty uncommon. More often what happens is the connection remains intact but communication/protocol/firmware/??? errors cause the device to stop working. It never disappears but it The difficulty here is that this "error" is indistinguishable from normal activity -- someone simply unplugs the device and then later on another connection is made. It might be the same device as before or it might be a different one. In other words, it isn't really an error. Interest...
