startup of linux very slow
 

Hi,
I very often have a slow startup of linux : after grub I have

(I am under Fedora Core 4, update kernel : this problem exists since always , with different kernels)

How to solve that ? What means this error ?
Thanks in advance

at grub press
ESC
and you can append extra settings

try
noapic

eg usually you have to boot linux
linux noapic


see if thAt fixes it.
if not try nodma

linux nodma

If it takes 20 seconds and it stops on the line about ide. It is trying to probe the hard drives even if there are none on either master or slave. I suggest adding hdX=noprobe to the kernel line of grub. Replace X with a certain letter. If ide1 has no drives, adding ide1=probe also works. Adding noapic actually makes some systems slower, but it can make a SATA drive boot up or make USB input devices work.

The "ide0 : I/O ressource 0x1F0-0x1F7 not free" is not good thing to see. I suggest going into the BIOS and turn off shadowing of BIOS and Video BIOS. If that does not work, take out one PCI card at a time to check if there is a hardware conflict that did not come up in Windows.

Thanks for your replies. I have tried adding the following options to the kernel at grub :
hda=noprobe
noapic
nodma
ide1=probe
==> I have still the messages "ide0 : I/O resource 0x1F0-0x1F7 not free and ide0 : ports already in use, skipping probe"
(Is it well after the line "kernel /vmlinuz-2.6.14-1.1644_FC4 ro root=LABEL=/ rhgb quiet" I have to aad the options ??)

I have found that the resource 0x1F0-0x1F7 is :
For info : I have scsi hard drive : sda. hda doesn't exist ; hdc, hdd = dvdrom / rw

Thanks for your help
