ext4 locks under 2.6.28.3..6

ext4 locks under 2.6.28.3..6

[Luciano Miguel Ferreira Rocha]

Hello,

I've experienced intermittent locks on my ext4 filesystems under kernel
2.6.28.3 till 2.6.28.6.

All mounted ext4 filesystems are locked, others keep working correctly.
I can't reproduce it at will, so I've been unable to do a bisect.

My current setup:

(sda1, sdb1) -> md0 raid1 -> ext3 /boot
(sda6, sdb6) -> md1 raid0 -> ext3 /
(sda2, sdb2) -> md2 raid1 -> ext4 /home
(sda3, sdb3) -> md3 raid0 -> luks -> ext4 /stuff

Mounts:
rootfs / rootfs rw 0 0
/dev/root / ext3 rw,errors=continue,user_xattr,acl,data=ordered 0 0
/dev /dev tmpfs rw,mode=755 0 0
/proc /proc proc rw 0 0
/sys /sys sysfs rw 0 0
/proc/bus/usb /proc/bus/usb usbfs rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0
/dev/mapper/luks-9f79b26a-6593-4009-acf6-ed3c5b191aae /stuff ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered 0 0
/dev/md2 /home ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered 0 0
/dev/md0 /boot ext3 rw,errors=continue,user_xattr,acl,data=ordered 0 0
tmpfs /dev/shm tmpfs rw 0 0
none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0
gvfs-fuse-daemon /home/luciano/.gvfs fuse.gvfs-fuse-daemon rw,nosuid,nodev,user_id=500,group_id=500 0 0
/dev/sdd1 /media/strlin ext3 rw,nosuid,nodev,errors=continue,data=ordered 0 0
/dev/loop0 /mnt iso9660 ro 0 0

(loop0 is a iso file under /stuff)

Are you still seeing the problem now that you're using 2.6.28.6?  It
looks to me to be another case of bug

http://bugzilla.kernel.org/show_bug.cgi?id=12579
http://bugzilla.kernel.org/show_bug.cgi?id=12610

As I commented in bugid 12610:

Yes, my report was after a lock just after upgrading to 2.6.28.6.

I'm currently on vacation till next week, so I haven't stressed my
system to see if it keeps locking up.
