------- Comment #1 from cascardo@holoscopio.com  2009-01-23 13:02 -------
Have you enabled flex_bg recently? Have you kept the log? Any message
indicating an error like this one?

Jan 23 14:20:42 vespa kernel: [  463.027499] EXT4-fs error (device dm-11):
ext4_get_group_desc: block_group >= groups_count - block_group = 11,
groups_count = 11

I've hit this bug and fixed it. The patch was sent to linux-ext4 and is
available at
http://holoscopio.com/patches/0001-ext4-fix-oops-when-online-resizing-a-filesystem-wit.patch.
Could you, please, test it?

Regards,
Cascardo.
