uname -a
Linux RIPLinuX 2.6.33.2 #1 SMP Thu May 27 10:56:32 EST 2010 i686 GNU/Linux

On Lupu 5.20

It has been working swell, so I'll leave it this way, I suppose.

I have RIPLinuxX installed on the same partition as Puppy frugal, and it appears that it is picking up the RIPLinuxX kernel and not the Puppy kernel, but even that doesn't make sense because I told grub were to find the kernel.

Now that I discovered this, I could fix it, but considering it has been working great probably won't.

~

I thought it worth mentioning that this phenomena maybe can occur, even though I told Puppy where to find things as shown below:

kernel (hd0,1)/520/vmlinuz ro pmedia=atahd psubdir=520 pfix=nocopy,fsck pdev1=sda2

That's all, just an announcement unless someone like Barry or an interested developer wants me to look into it to try and figure out why. Or hopefully, someone already knows how this could happen.

Doesn't the Puppy kernel has something like

Question
Not sure though .

Had a look here :
http://distrowatch.com/table.php?distribution=rip
and
http://www.tux.org/pub/people/kent-robotti/looplinux/rip/
For the moment it seems to me that the rip and puppy kernel are unintended twins by their respective "make" rs .

RIP is some 160 MB, think I will dl it .

Thanks for pointing me to it .

bash-3.2# strings vmlinuz-orig | grep EST
2.6.33.2 (root@puppypc) #1 SMP Thu May 27 10:56:32 EST 2010

bash-3.2# strings /boot/vmlinuz-orig | grep GMT
2.6.30.5 (root@puppypc) #1 SMP Tue Sep 1 15:48:26 GMT-8 2009

All my kernels that i had compiled on Iguleder's dpup two years ago had GMT-8 because i had omitted to set the local time back then . It had been the 2.6.33.2 kernel running . Will have to check . There are i think several updated kernels for 2.6.30.5 because aufs had been updated but not for 2.6.33.2 as it seems on http://bkhome.org/sources .

Hmm.. seems that woof is capable to recompile the kernel .

DOTconfig-K2.6.33.2-5APR2010-SMP-TICKLESS is on Barry's site
and the vmlinuz :

Thanks very much for the interest

Here are some more details.

My hard disk doesn't work when cold, as in room temperature. I normally run the computer 24/7

If I boot the machine cold, the hard disk is not identified or located. After a few minutes, it warms up. I reboot it and it stops at the GRUB menu.

I've learned I have to wait more minutes before booting. The partitions may not be ready.

One day, I booted Puppy and the on screen text indicated RIPLinuX was trying to load but in a disorganized hodgepodge of goodness knows what software. And it failed to boot and just locked up at a point.

I rebooted and it happened again.

In looking at the on screen text output, I thought something is horribly wrong and maybe making a mess of my partition.

I booted again and this time Puppy booted and I've never had a problem since.

I only discovered the RIPLinuX kernel is running a couple days ago.

GRUB specifies kernel (hd0,1)/520/vmlinuz

but it uses: kernel (hd0,1)/boot/vmlinuz

This would seem to me a GRUB problem. BTW it is a hacked GRUB version 0.97

Do you think?

~~~~

What about the hard disk not being functional when cool?

It doesn't necessarily have to be the hard drive, it could be something in the motherboard or its IDE controller.

The best way to check would be to buy a new hard drive. Because the hard drive can be used on other computers, but if its the motherboard, I'll scrap the machine, and remove reusable hardware.

After posting this 'bug' I think to myself the problem may be unheard of and unique to my machine.

I've also done a full e2fsck check on the partition with no apparent problems found.

~~~~

Thoughts?

Another thought of mine would be that you are running RIP linux with the Puppy kernel . In my experience it is likely that a kernel boots and a Distro gets up til the X-Desktop but without any additionally modules loaded .

Would be interesting to see lsmod output .

Thaks for the interest Karl

It is running Puppy for sure, because the software, desktop and apps are all Puppy. Even the loop devices:

Intriguing Bruce

It has been found that hostname conflicts can slow down your PC. Is all performing OK?

I did research on this when we went over to a unique hostname setup in woof by appending ${RANDOM} to "puppyc" very early on in the initial boot.

Different ways to determine hostname in puppy:
Code:
# hostname
puppypc16509
# uname -n
puppypc16509
# cat /proc/sys/kernel/hostname
puppypc16509
# sysctl kernel.hostname
kernel.hostname = puppypc16509
# cat /etc/hostname
puppypc16509
# grep $HOSTNAME /etc/hosts
127.0.0.1 localhost puppypc16509
# echo $HOSTNAME
puppypc16509


If it changed by itself I wonder how?

It ran fast and then slowed down after the ISP made some changes, I know what they didn't do right, just need to call them out. The slowdown shows up mostly when watching Youtube videos.

Here are the results of the tests

[~] hostname
RIPLinuX
[~] uname -n
RIPLinuX
[~] cat /proc/sys/kernel/hostname
RIPLinuX
[~] sysctl kernel.hostname
kernel.hostname = RIPLinuX
[~] cat /etc/hostname
localhost
[~] grep $HOSTNAME /etc/hosts
127.0.0.1 localhost
[~] echo $HOSTNAME
localhost
[~]

The $HOSTNAME may of been something like puppypc and I may have changed it myself to localhost

But

I didn't change the kernel or anything to do with it.

Bruce

Bruce B, do you hear a clicking sound while your hard drive is being slow? That would tend to indicate impending failure of the drive.

...could also be that the controller on the computer's motherboard is on its way out.

Even more intriguing! Since it looks like this behaviour has been there for awhile there is probably no way to trace what happened.

I would suggest that "localhost" is probably causing more conflict.
Code:
# hostname --help
BusyBox v1.19.3 (2011-11-09 07:34:50 WST) multi-call binary.

Usage: hostname [OPTIONS] [HOSTNAME | -F FILE]

Get or set hostname or DNS domain name

   -s   Short
   -i   Addresses for the hostname
   -d   DNS domain name
   -f   Fully qualified domain name
   -F FILE   Use FILE's content as hostname

# hostname -d
# hostname -i
127.0.0.1
# hostname -f
localhost


I would change the hostname! Get things consistent, see if they stay persistent.

Cheers

I don't think the hard drive runs slow. It just won't work right until its warm.

The hard drive is a WD 80GB IDE

I bought a WD 160GB IDE to replace it. If this doesn't fix it, I suppose off to the County Coroner for an autopsy.
