Comment 5 for bug 330824

I have experienced something similar to the first poster: I installed ubuntu 9.04 alpha 5 last week on a newly formated ext4 partition. As I was setting the system up, I was updating the system with the latest package updates but I kept running into an error saying the drive was full (it was actually at 20% full of 160 GB). Tried moving and deleting files off the drive, nothing worked. Eventually a reboot solved this but I don't know why.

Upgraded to kernel 2.26.28-9 (alpha 6) on Friday. This weekend I went about converting 2 x 1 TB data drives to ext4 (from ext3) and all went initially well but I wanted to get the full extent (no pun intended) of ext4 file structure so I was cut and pasting data back and forth between the drives using nautilus but the OS kept freezing. Eventually I figured out that copying and pasting was fine but deleting was the culprit. I tried deleting in nautilus and that hung the OS. Tried in a terminal, same thing. Booting into recovery mode and down to the root prompt and went about deleting these files and got a series of these: "BUG: soft locking - CPU#0 stuck for 61s!"

In the end I managed to completely clear one drive off so I reformatted it and then transferred everything back and then reformatted the other. Now both TB drives have "native" ext4 partitions and I can delete from those drives without hangs or freezes.
