PowerPC has hotswap for Motorola boards thanks to Johnnie Peters and Matt

Well the code does a fnsave. Somebody never looked at the damn book! it
Oh I did. And then I timed the performance for the copying cases

When I run this and check the valur of virt and phys, it appears that phys is

I would like to upgrade my kernel which is bundled with Red Hat. However,
I don't want to lose modules/functions it has complied. How can I do
it? Is there any command to check the current config and how can I check
the modules it has as well?
The Red Hat bundled source rpm package contains

Ok, I understand the problem.
Can you elaborate some more on exactly which files go in "core",
"hosts", and "upper"? My understanding is:
# drivers/scsi
scsi-core-files := scsi_mod.o
If a kernel hangs early in the boot process (before the console has
been initialized) then printk is no use because you never see the
output. There is a technique for using the video display to indicate
boot progress so you can localize the problem. Reporting "my kernel

Linux 2.4.0-test6 i386
I've just put a manual arp entry in for 192.168.56.1.
arp -n does not show it.
/proc/arp
has the following line
192.168.56.10x10xc etc
where the ipaddress and the HWtype are jammed against each other.
dare i suggest this might be a bug?

Hi Daniel,
tar -cvf /dev/f1 .
Take a look at the line before it:
tar:
tar -cvf /dev/f1 .
This goal has been in the net/*/Makefile files a very long time. I see
it in linux-0.99.1.tar!
My guess is that the original author/user of this little goal liked to
back up

LVM and MD have nothing common. They're two completly orthogonal
piece of code
Right. Functionally they overlap (lvm can do the equivalent of md
linear) but structurally, the md drivers all operate under the md
framework and user-toolset while lvm has its own framework and toolset.
Hi again,
Further hints.
More testing (printks in refill_inactive and page_launder)
reveals that refill_inactive works ok (16 pages) but
page_launder never succeeds in my lockup state... (WHY)
alloc fails since there is no inactive_clean and free is
less than MIN. And then when page_launder
