what is it that triggers this crash? there have been a lot of successful i386 ISO tests in the past day which included this code - so this must be a corner case... what corner is it in?

I believe I'm also hitting this bug, Ubuntu 9.10 is crashing every time I attempt to install it to a SATA disk.

Is there any way to apply this fix before starting the installation?

[myxiplx (myxiplx)]

Nevermind, the fix is stupidly easy:

- Boot the Live CD
- Connect to the internet
- Use Update Manager to download the latest updates

You can patch the installer from the Live CD.... wow.

Very, very smooth guys.

I passed it simply installing in textmode - and ewerything was fine.
IMHO, patch should be included in upstream builds.
