I've updated it again from internet, second hdd doesn't get mounted until I've changed it (/dev/hdb1) in /etc/fstab with /dev/sdb1. CD/DVD aren't mounted automatically and GnomeBaker recognize it with a new path, /dev/sr0. I don't know why the guys from Ubuntu made these changes.
At start-up this time I was warned just once about VirtualBox crash (a little improvement from last time Smile ).
Now is the last time when I try to install Ubuntu8.04, so I've downloaded an alterate cd. If even this installation fail, I have no other choice than to remain to 7.10, wait until come the original cd from Ubuntu or try another distro.

Now a funny moment with Ubuntu8.04, it gave extra-speed to my dvd-drive while burning alternate cd.index.php?t=getfile&id=1179&private=0

Well, now my problems with Ubuntu are solved due to help from mdelfede. Thanks.
My problems where mostly because of some malfunction of cd/dvd-rom DMA with current kernel.

Hi folks - new here.

Just registered to ask if bytefield or mdelfede could help out.

I'm having problems with getting the same error as mentioned above.

When I use 2 fairly recent CD drives, it bombs out. But when I use an older one it works ok up until the drive itself stops working. It's a faulty drive.

So what could I do to get the newer drives to co-operate?

Any help greatly appreciated.

Thanks,
Jonathan

I was just deactivated the DMA from BIOS. It was a partly solved problem. Three weeks ago my CD/DVD drive get burned and I've got another drive (Asus), i don't know if that one is exactly like first but my problems are gone and I can use drive without deactivating DMA.

P.S.: I don't know if mdelfede will answer because he will be away for few days. So try to deactivate DMA and/or 32 bit transfer mode from BIOS. However that don't solve the problem at all, because it will cut some speed from CD/DVD drive. Better that than nothing Rolling Eyes . I wish you have luck.

Thanks for your reply.

I actually found another thread on ubuntuforums suggesting that I add all_generic_ide to the boot options.

This solved my problems. Thanks anyway.

p.s. I'm liking KDE4

To be honest I don't know. I've not looked for the reference on boot options.

But all the complications seemed to stem from the DVD drive which is an IDE device... so something related to that.

If anyone knows.... share the wealth.

When i was trying Linux first time(some years ago) the KDE was quite instable, back then the Gnome attracted me by simplicity and the number of programs written for it (using gtk+).
I tried KDE4 some times ago, it's eye candy and enough stable... but i didn't use it as main desktop...

After some research I found that all_generic_ide does this in init script:
if grep all_generic_ide /proc/cmdline 2>/dev/null; then
	        modprobe -v ata_generic all_generic_ide=1
	fi

kernel module ata_generic's source describes it as:
/*
 32  *      A generic parallel ATA driver using libata
 33  */
