After attempting to boot the Ubuntu 8.10 Intrepid Ibex "ubuntu-8.10-desktop-amd64.iso", I am dumped into an initramfs prompt. It seems casper is failing to mount the livecd on /cdrom.
I have been having troubles booting the 64 bit livecd's on my AMD Athlon X2 4050e Dual-core system. I believe the problem lies in either the cdrom drive itself, or there is some reason that my drive is not being mounted during the livecd bootstrap process.
I have tried re-burning the disc again (final time burned at a slower speed 8x), and re-verified it's iso image again on another system before booting.
With the first (possibly bad) disc burnt at 32x, I did not get dumped into busybox immediately, but instead got some read errors from the drive first:
[ 70.050980] Buffer I/O error on device sr0, logical block 357904
[ 78.308803] end_request: I/O error, dev sr0 sector 1431616
[ 78.308856] Buffer I/O error on device sr0, logical block 357904
[ 85.123577] end_request: I/O error, dev sr0 sector 1431616
[ 85.123627] Buffer I/O error on device sr0, logical block 357904
[ 91.938358] end_request: I/O error, dev sr0 sector 1431616
And so on...Pressing Ctrl-C at this point dumped me into busybox prompt. Reading "casper.log" for this disc said:
/init: line 1: cannot open /dev/sr0: no such file
/init: line 1: cannot open /dev/sr0: no such file
/init: line 1: cannot open /dev/sr0: no such file
.... SNIP...
Unable to find a medium containing a live file systemI decided this disc may be a bad burn, so I tried another burn, this time at 8x speed. After burning, I re-read the disc on a windows machine, and used cygwin with "readcd.exe" to dump an ISO file. I checked md5sums and it was identical to the original source ISO.
With the 8x disc, I am dumped into buysbox. Reading the "casper.log" file shows:
mount: mounting /dev/scd0 on /cdrom failed: Invalid argument
mount: mounting /dev/scd0 on /cdrom failed: Invalid argument
mount: mounting /dev/scd0 on /cdrom failed: Invalid argument
...SNIP (Repeated MANY times)...
mount: mounting /dev/scd0 on /cdrom failed: Invalid argument
Unable to find a medium containing a live file systemIs there something wrong with my drive? This system has been able to boot the i386 disc for Ubuntu 6.10 Edgy Eft fine! Currently the system has an install of gentoo x64, which was put in place by it's previous owner. I wish to switch it to ubuntu x64.
Any magic boot flags that may help in this case?
