Bug Description
Binary package hint: e2fsprogs
Hello, I hope it's the good package I write this bug for. Currently as You can see i'm back to ext3 file system.
But when I try to install 10.04 with standard ext4 sometimes already a freeze occur during install proces when formatting HD. Sometimes it work's but take's very very long to format.
Once installed, (with ext4) Everything seems to be fine, except that the whole system freezes sometimes instant. It is very random and sometimes pc work's a week whitout a freeze other days it freezes 3 times a day. I did checked all ram update bios and so one, even in despit of good ram test's I even tried with other ram. Problem in all cases the same. The only option after freeze is a hard reset. There is no log information about what went wrong. But there was one thing which happende after each reset when I had a freeze . Into dmesg I found
[ 4.868112] EXT4-fs (sda1): INFO: recovery required on readonly filesystem
[ 4.868115] EXT4-fs (sda1): write access will be enabled during recovery
[ 6.110195] ieee1394: Host added: ID:BUS[0-00:1023] GUID[002b7aa800

[ 7.182905] EXT4-fs (sda1): 7 orphan inodes deleted
[ 7.182907] EXT4-fs (sda1): recovery complete
This was not there when I did normal shutdown and restart.
If I put the ram speed down into the bios freezes are less frequent but occur still especially when performing large data transfers.
When formatting with ext3 everything goes fine and never a freeze occur. Looking around on the web I found similar problems into ubuntu forums. The common faktor seems to be that they all occur when using fast ram and fast hd's with ext4 file system.
For me using WD raptor HD seems to be touched by that problem.
It look's like there is some were a runtime problem when writing and or reading to EXT4 formated drives which only occurs using fast ram in combination with fast HD.
I even think that it can be solved by changing some were a small rule into ext4 source. But due to the small amount of info after the freeze occur, now it wil be very difficult to find.
The only thing I can deduct that at each freeze some garbag was written to the ext4 HD.
If other persons are affected by this bug, I suggest that you use ext3 for the moment.
Hoping that there is enough info here ( i'm well back to ext3 now )

Ram at max speed now runs perfect under ext3
Ram test even after 3 passes error free.
