Description of problem:
seems as though when bootup procedure gets to the loading of the usb
support after the "Welcome to Red Hat Linux hit "I" for interactive
startup" message it just throws a bunch of junk on the screen and
complains about the interrupt handler or some sort of kernel error and
locks up to the point that i have to power down. maybe this is a known
Version-Release number of selected component (if applicable):
Red Hat 7.2
Steps to Reproduce:
happens on bootup
Is this an athlon cpu machine ?
If so, does it help if you type "noathlon" as extra kernel option in grub (or
add it to the lilo prompt if you use lilo)
yes it is an athlon machine
athlon 1.4 cpu
abit kt7-a mother board
and i have unplugged all usb devices and even disabled usb in the bios to no
ok please try the "noathlon" thing
in grub type "e" over the kernel, go down one and edit that line to add noathlon
to the end of the line, <enter> and then <b> for boot.
If that works, I'll help you make that permanent
ok!@##$ that worked, it got me booted up and led me to hardware mangaer where i
removed the VIA usb device.i sure would like to now more about this issue though :).
ok the basic issue is that some bioses tune the VIA chipset beyond the memory
bandwith it can handle, and under certain uses it does things wrong then.
The kernel uses a very fast memory-copy routine optimized for athlons that
triggers this condition, the noathlon option avoids using this routine, and
hence avoids the "things go wrong".
We're talking with VIA about it for a while now, and people on the linux kernel
mailing list have found a setting in the chipset that makes a differnce,
unfortionatly this setting is undocumented in the chipset documentation so we
don't know if it's harmful or not.
For your situation there are 2 options: installing the i686 kernel instead of
the athlon kernel, or keep using "noathlon".
To do the later, open /boot/grub/grub.conf in a texteditor (as root) and add
noathlon in the place you used for booting before.
very good sir. i thank you dearly for your time
have a good day!

wohoo helped me out...but how can I install with the i686 kernel? And why Red
Hat gotta be playa haters? :P
Also note that the 2.4.9-21 kernel has a fix to undo the damage the bios has
