Re: slow kernel when memory = 8G

I am the original poster. Thanks for everybody for trying to help.

We have a new box which has 8GB of memory. (Debian 3.1).
When we use the original Debian kernel, it works fine,
but it sees only 4GB memory. We compiled a new kernel
for ourselves, and we changed the "High Memory Support"
to 64GB. Now the system bootup is horribly slow. With the
original kernel it took less than a minute, now it takes
an hour at least. For example, there is almost minute gap
between the "ide..." and "hda..." detection. With the
original kernel, it was practically instantaneous. These
slowdowns are all over.

Some of you rightfully complained that I didn't provide enough
info. Here are the relevant infos:

The kernel config file was grabbed from /boot/ (2.6.8) which
came from Debian. My co-worker (who compiled the kernel) just
changed the memory 4GB to 64GB. That's all.

Anyways, here is a part of the .config file. I removed everything
I considered unnecessary.

Also, we tried to specify the memory size on the boot
command line, and we figured, that the system saw
2.5GB (+-100M) less than we told it. Finally we passed
10G, and now the system sees 7.6GB, and it is ok now.

Anybody can help?

I hope now I provided enough info. First I didn't include them since
I thought that this might be a known problem with a (hopefully)
quick solution. Well, this was not the case.

Again, thanks for everybody for the effort. I will try to figure
out what's wrong and post the results.
