Grub 1 troubleshooting, linux boot delayed problem

Grub 1 troubleshooting, linux boot delayed problem

[David Balazic]

Hi!

I found no other place, so I'll ask here.

I have a problem booting linux with grub ( v 0.9.something ).

I use the commands ( in the grub shell that boots from my HD ):
root (hd0,0)
kernel /vmlinuz-2.6.xxx ro root=dev/hda2
initrd /initrd-2.xxx
boot

After entering the "boot" command, the screen is cleared and then nothing
happens for 93 seconds.
After that linux boot normally ( beginning with the message "Uncompressing
linux..." and so on ).
If I trim the kernel command line to only "kernel /vmlinuz-2.6.xxx ro" ,
then the delay is 10 seconds.

If I change the operating mode of the IDE adapter in BIOS to RAID, then the
delay is infinite ( I waited
8 hours ). Note that GRUB still loads andit can browse and "cat" files on
the disk, so it is not a disk
access problem.

Can someone tell me how to find out what GRUB is doing after the "boot"
command ?
I tried to run "debug on" first, but it makes no change at all.

Maybe this is a linux kernel problem.

Any help appreciated !

Regards,
David Balažic

P.S.: It is a Fedora Core 2 system, the exact version numbers are
grub-0.94-5 , kernel-2.6.5-1.358

P.P.S.: I know this is Red Hat related, but my question is general : What is
happening between
the GRUB "boot" command and linux printing "Uncompressing linux..." ?

grub spends ages probing the actual physical devices to use
if you don't specify a device map. Try doing this first:

device (hd0) /dev/hda

You may also have to specify a geometry?

What probing ?
I specified (hd0) and it also worked ( can access and read files form disk
).
Why would it probe, especially after it already loaded everything.

Will try.

Your question is irrevalent with this list. Read the manual and/or the 
web site for information on where to use.

... Why do people send questions to this list again and again? Is it so 
unclear?

What do you mean by "where to use" ?
I found nothing useful on the web site. I also read the manual and found
nothing
useful. I will read the source code as next, but I hoped someone can give
some hints
here first ...

Because there is no other resource listed on the GRUB home page. Or should I
post
to the bug-grub list ?

Could you tell me how you interpreted this paragraph? I'd like to know 
this to improve the paragraph. I guess there must be something bad in 
the web site, since so many people misunderstand it.

I checked the Bug Tracking System  and the FAQ and the manual, none of it
helped,
so I decided to ask someone. And that someon it this mail list since no
better choice
was mentioned on the web site.

Improvement :
 - in text "read the chapter Reporting bugs in the manual." the words
"Reporting bugs"
  could be a link to the corresponding part of the manual

"Once you have realized ..." interesting choice of words ;-)


Besides, I tried a to boot another, older kernel and it does not have the
described problem,
so you can all calm down, this is not a grub problem, but a linux kernel
problem.

Sorry for wasting your time.

David

And I asked myself the same question several times.

How about these possible causes:

- The GRUB 2 section is the first that appears.  When looking for a
  mailinglist it is the first list that appears.  
- Perhaps it's how people think.  If you have to choose between
  bug-grub or grub-devel, what would you choose?  I would first figure
  out what would be the right list, but it seems people don't do this.
- `GRUB Legacy is no longer under development. This means GRUB Legacy
  is soon to become abandoned and the only modifications made to it
  will be in regards to bug fixes.'  That sounds like it is an
  abandoned, old version no one uses.  I think many people don't know
  or care which version they use.

I will think about how to change this later this week and propose a
solution (+patch).

Create a grub-users list and advertise it on the web page.
