Public bug reported:
The default kernel entries in GRUB's menu.lst have parameters both on
the end of the kernel line and as a separate line.
For example, from my installed 7.04 system:
[[
title Ubuntu, kernel 2.6.20-16-generic
root (hd0,8)
kernel /boot/vmlinuz-2.6.20-16-generic
root=UUID=35065adf-6d54-4af8-bd91-0d0431429c1f ro quiet splash
initrd /boot/initrd.img-2.6.20-16-generic
quiet
savedefault
]]
Note how "quiet" is on the end of the kernel line *and* on a line of its
own after the initrd line.
While trying to trace booting problems, I removed the line reading
"quiet", but still got a quiet boot, as there was a duplicate
instruction on the kernel line as well.
When I manually added parameters as a new line on the end of the entry,
using GRUB interactively at boot time, that said "nosplash acpi=force
irqpoll", the machine consistently rebooted when I tried to boot. I
think this is because my "nosplash" parameter conflicted with the
"splash" parameter on the "kernel" line.
Should such parameters be duplicated like this? It means that entries
must be changed in 2 places to get a successful boot. Conflicting
parameters seem to cause GRUB to reset the PC.
