I am working on a project which will require a lot of CPU power. I will
be running TCP, a managable number of busy threads, and gigabit ether.

First it does not work because you do not have access to libc in the
kernel. Secondly your LCD driver is not available at the time of
start_kernel so there is no one to listen to the /dev/lcd.
The quickest hack would be to find your lcd driver and modify it to spit
out the Loading Kernel, after

Hi CJ,
you should really read the thread titled "Linux's implementation of
poll() not scalable?" in the LKML archives, here is a link:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0010.3/0003.html
There are many problems with the /dev/something interface for events and
all is described in that
There is a great article here:

jiffies is updated by a timer interrupt once every 1/HZ seconds (HZ==100
for i386).
The code intents to start running at the time right after jiffies was
incremented to improve the correctness of the delay calibration loop.
The reason why jiffies is read later is to get the value after the

BTW this is also the case for AMD-K6-3 and I would imagine all other AMD

What kernel are you running? This is disabled by default. search for
where FASTRETRANS_DEBUG is enabled (should be in linux/include/net/tcp.h
and set it someting low (like 1 which is the default. The actual error
message comes up in tcp_input.c (search fro FASTRETRANS_DEBUG).

Hey, I am looking for some TCP benchmarks for the 2.4.x sersies of
kernels. I am interested in # of new connections per second and impact
of backlogged connections. Memory constraints are also of interest.
An URL or just word-of-mouth stats will do.

I see benefit in having the .config file in the kernel. It being a non

it available as a proc entry.

I am running 2.6.23.1 with kvm built from that tree as a module. My
system is running Debian/testing on a Tyan board with two dual-core
Opteron 2216 processors; each socket has 4G of RAM. I have attached the

A bisect didn't find anything between 2.6.22 and 2.6.23. Which made me

This time I booted with "maxcpus=1" and proceeded to build 2.6.19-rc
One more update. I rebuilt 2.6.19-rc6 and turned off CONFIG_PREEMPT_BKL.
It didn't help much.
I am still getting BUG dumps from the kernel, however they don't cause
freezes immediately. It takes a few minutes of console output before
the computer stops responding to my input.

Hello,
I've been getting odd crashes in 2.6.18 and .19-rc's with a dual core
opteron on an nforce chipset. I've been running with a serial console
capturing things.

I need to preserve some state from the bios before entering protected

say the last megabyte visible in real-mode.
What's the easiest way to have linux ignore the megabyte starting at 15M?
Cheers,
