Description James Laska 2008-07-29 13:39:49 UTC
Description of problem:

Installing rawhide (2008-08-29) stalls during package install.  Inspecting the
console shows a kernel error.

Version-Release number of selected component (if applicable):

* anaconda-11.4.1.20-1
* kernel-2.6.27-0.186.rc8.git15.fc10
* e2fsprogs-1.41.0-1.fc10

How reproducible:
100%

Steps to Reproduce:
1. Boot rawhide installer with 'ext4' command-line arg
2. Select autopart and review partitions
3. Change '/' to a ext4dev
  
Actual results:

Package install hangs during installation of glibc-common package and a kernel
bug is displayed on the root console (see attachment)

Expected results:

Installation completes without error

Comment 2 Eric Sandeen 2008-07-29 13:55:35 UTC
EXT3-fs: sda2: couldn't mount because of unsupported optional features (40).

Which filesystem was sda2?

EXT4-fs warning (device dm-0): ext4_fill_super: extents feature not enabled on
this filesystem, use tune2fs.

and was this the root fs?

Thanks,
-Eric

sda2 should be a ext3 /boot

> and was this the root fs?

'/' is a logical volume

Comment 5 Bug Zapper 2008-11-26 02:37:04 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

I don't know if this is relevent but in my /var/log/messages I am getting many messages like this.

Are you running the debug kernel?

Comment 8 Eric Sandeen 2009-06-30 21:01:22 UTC
A lot of changes have happened since .27, and apparently this is fixed, given that we shipped ext4 as default fs in F11 :)
