Hope this is actually a bug and not me being useless - On an S10 Lenovo laptop the boot fails, crashing to ramfs after attempting to find a boot disk and trying to load /media/sr0. MD5SUM for the CD was checked, and the CD can boot another laptop. This is using a USB cdrom drive. The 2008 release works fine, and that is what I'm using at the moment. What checks can I do to provide useful information?
This task depends upon

This is the section of the boot sequence where it stops:

Does this happen with the installCD itself or on the system you installed with it? (if the latter: which installer did you use?)

It seems like you have an invalid ext2 FS somewhere.

@Aaron do we do automounting of any filesystems somewhere?

sr0 is the cdrom device, and it fails to mount for some unknown reason.
Hmmm...

Is it usb attached? Perhaps try adding a usbdelay=10 entry or something.... maybe it needs more time to spin up

Ah, I missed the part where you said it was a USB cdrom. Try increasing the usbdelay to something like 10 or even 15

Thankyou gentlemen, increasing the usbdelay to 15 seems to have fixed the booting issue.
