I upgraded to e2fsprogs-1.40.4-f last night and had a lockup. I did an
unclean shutdown of my rawhide system. When I rebooted back up I received
the error
"Primary superblock features different from backup, check forced"
The system did an fsck and rebooted , just to have this process repeat
continuously
I was reading that this was inded a bug in e2fsprogs
The e2label feature discusses here
http://archives.free.net.ph/message/20071002.193847.a68af972.en.html
didn't fix the problem (I booted from a F7 cd to rescue)
I just wanted to report that this bug

Seems to apply to e2fsprogs as of yesterdays version
