Since you marked it as a regression, what was the last working kernel?

I upgraded from 2.6.32-rc5, where I didn't see this issue. 2.6.32.3 works
fine on the same machine and filesystem.

I'm not using 2.6.33 anymore since this bug is a showstopper to me (it's on a
production system), so I'm unable to check if it's fixed or not.

Well, in that case I'll have to close it as 'unreproducible', because no one
else seems to be able to reproduce it.

Hi Steiner,

Sorry for not getting back to you right away; I've been doing a huge amount of
travel right during January.   Can you tell me something about the file system
workload on your machine?  What does it do?  NFS, rsync server, backups, ...?  
And do you know what it might be doing right before it crashed?   How easily
can you reproduce this?  I take it since you had to stop using 2.6.33-rcX you
could reproduce it easily?

If you are willing to try a 2.6.33-rcX kernel, I'd suggest seeing if "echo 0 >
/sys/fs/ext4/<dev>/max_writeback_mb_bump" makes the crashes go away.

IIRC this was a file system that was mainly used for video storage and
transcoding -- I think I was encoding a video with x264 to it when it
crashed. Apart from that the machine spends most of its I/O time doing web
serving from relatively large (1-2TB) data sets, and occasionally rtorrent.

It was recently online expanded, so I thought that might be related, but the
problem persisted after a reboot and a forced fsck, so there was no on-disk
corruption involved.

It crashed two times in two days or something after I upgraded to 2.6.33-rcX.
Not a statistically huge sample, I'm afraid.

I'm afraid it's not so easy for me to do reboots into new kernels on this
machine; kernel upgrades generally happen when the machine is booted for some
other reason. :-/

This type of lock dependency is always going to exist whenever a write to 
a sysfs file causes the kernel to remove its dirent.  In this case, 
writing to /sys/devices/block/xxx/queue/scheduler takes sd->dep_map and 
sd->parent->dep_map via sysfs_get_active_two() to pin both via 
sysfs_write_file().  The call to kobject_del() removes its directory 
from the hierarchy which takes sd->dep_map in sysfs_deactivate() because 
of 846f99749a.  Eric, do we need to preempt the rwsem from being acquired 
here when the dirent is already pinned because of a store to one of its 
files?

Hmm.  The bug is in net/dccp/ccid.c, so it looks like something for the
networking guys to merge.

Any chance to send a singed-off version of the patch do David?

The regression compared to 2.6.32 is solved in 2.6.33-rc7 for the
specific test mentioned in the Bugzilla entry. The regression compared
to 2.6.28 is not yet solved though, so I'm not sure what should happen
with this bug entry.

I guess it's better to move it to the list of regressions from 2.6.28.

Fixes for this are already in my net-2.6 tree, will send them
off to Linus later today, I was waiting for some netfilter

    dccp: fix auto-loading of dccp(_probe)

    Fix module load dependencies between dccp and dccp_probe", from 15 Jan).
    
    It fixes the construction of the first argument of try_then_request_module(),
    where only valid return codes from the first argument should be returned.
    
    What we do now is assign the result of register_jprobe() to ret, without
    the side effect of the comparison.

[Bug #15025] Oops in ext4 driver

This message has been generated automatically as a part of a summary report

The following bug entry is on the current list of known regressions

There was a power drop (too long for the UPS), so I've now run 2.6.33-rc8 on
this same machine for about 24 hours without seeing any ext4 errors. The load
is probably different, though, but at least it doesn't seem to bite me anymore.

It i is posible to triger the bug without quota.
Untill the patch it we have following code
fs/ext4/inode.c:
1850         if (ext4_claim_free_blocks(sbi, md_needed + 1)) {
1851                 vfs_dq_release_reservation_block(inode, md_needed + 1);

1853                 retry:
1854                         if (md_reserved)
1855                                 write_inode_now(inode, (retries == 3));
^^^^^^^^^^ Here we goes in to lack of journal credits. ^^^^^^^^^^^^^^^^^^^^^^
1856                         yield();
1857                         goto repeat;
1858                 }
1859                 return -ENOSPC;
1860         }
You have failed exactly here.
So the bug happens even in case of ENOSPC (try following testase):
dd if=/dev/zero /mnt/BIG_FILE bs=1M 
But it takes longer if partition is really huge.

[Bug 15025] Oops in ext4 driver

Since  calling "write_inode_now" from ext4_da_get_block_prep was the core of
the issue. And the patch move it to an upper level. So the issue was completely
fixed. Please close the bug as CODE_FIXED
