It looks like something's passing a negative partition size to partman. Could you please run the installer with 'ubiquity --debug' from a terminal window, reproduce this problem, and attach /var/log/installer/debug, /var/log/syslog, and /var/log/partman to this bug, following the directions in http://wiki.ubuntu.com/DebuggingUbiquity/AttachingLogs? Thanks in advance.

Interesting, ubiquity --debug itself crashed in id 20070322
I will resync with 20070325 and try what you asked.
I vim'd the ubiquity python script and found no --debug flag
but since I dont know much about python that could be just fine.

I will post after the test with 20070325 later tonight.

It might help you folks if you know this.

When I run parted /dev/sda (as root) from the
command line and execute

resize 1 0 20%
I get the error
Error: File system has an incompatible feature enabled.

The file system in question was created by
20070322 ubuntu installer,
Option
Guide me- use entire disk

Actually any parted resize I try to do no matter what the params it fails with the
incompat feature enabled error above.

hope that helps some

Thanks. This is also bug 95400, which I'll fix shortly.

It's normal that you can't use 'resize' from a parted shell to resize these file systems; partman works around libparted's lack of support for this by doing it in resize2fs. The problem was a different one, namely that the shell's arithmetic operations were using 32-bit numbers rather than 64-bit ones and so the size calculations all came out wrong for large partitions.
