Compiling new kernel - problems on boot up

Compiling new kernel - problems on boot up

Post by mobi » Wed, 12 Dec 2001 22:02:31



Hi all !
ok, i installed redhat7.2 the other night and found that by default,
the kernel does not support NTFS. So i tried and comiled myself a new
kernel with that option 'on'... but ran into troubles.
Preliminary INfo:
distrobution - redhat7.2
kernel - 2.4.7-10
boot loader - GRUB

I think i compiled my kernel properly, but when i 'enable' my new
kernel in GRUB, and start my boot sequence, it stops at this line:

uchi.c:USB UCHI at I/O 0xd000,IRQ 12

I am confused. I dont really know what to do next. Luckiliy i still
have my old kernel so its not a big deal but i am still really stuck.
Does that line mean anything special? Or could it be just a random
line that it stops at?

Also, re:GRUB.
I am new to GRUB - I have always used LILO, and in the
/boot/BRUB/GRUB.conf when i entered the lines in for my ner kernel, i
didnt know what to include for the line that contains the ".img"

When I created my kernel, i got my bzImage and all that jazz, but no
".img"
WHat do i enter in that line in GRUB? Do i leave it the same as my
main kernel? GRUB is already pointing at bzImage, i know that , but
its a different line in GRUB that i wam wondering about.

THanks for ANY help you can give - maybe even detailed GRUB docs?

CHeers,
David

Offhand it looks like a resourse conflict.  The easiest thing to do is
to turn off all USB support in your kernel config. file, and
recompile.  Of course, it could be that you need USB support.  In that
case, I would get the latest kernel, and compile anything to do with
USB that you need as a module.  Afeter booting your new kernel, insert
the modules that you need using insmod, and you may be able to find
the problem.
     Of course it is possible that this has nothing to do with USB
wanting to hog IRQ's.  In that case you will fond the same problem,
but your machine will lock up with a different last line.  But at
least this is a place to start.
     I'll let more sage heads than mine deal with the GRUB problem:
my solution  of just installing LILO might not appeal to you.
