Hello,
i have now used aufs for a very long time, and it was working perfectly!
But now with the update from this monday i have a problem. With the
version from last week everthing was working well.
This is my configuration:
CONFIG_AUFS = m
#CONFIG_AUFS_FAKE_DM = y
CONFIG_AUFS_BRANCH_MAX_127 = y
CONFIG_AUFS_BRANCH_MAX_511 =
CONFIG_AUFS_BRANCH_MAX_1023 =
#CONFIG_AUFS_BRANCH_MAX_32767 =
CONFIG_AUFS_SYSAUFS = y
CONFIG_AUFS_HINOTIFY =
CONFIG_AUFS_EXPORT =
CONFIG_AUFS_ROBR =
#CONFIG_AUFS_DLGT = y
CONFIG_AUFS_RR_SQUASHFS = y
CONFIG_AUFS_SPLICE_PATCH =
CONFIG_AUFS_PUT_FILP_PATCH =
CONFIG_AUFS_LHASH_PATCH = y
CONFIG_AUFS_SYSFS_GET_DENTRY_PATCH =
CONFIG_AUFS_KSIZE_PATCH =
CONFIG_AUFS_WORKAROUND_FUSE =
CONFIG_AUFS_DEBUG = y
CONFIG_AUFS_COMPAT =
Normally i a using CONFIG_AUFS_DLGT, but to make things easier, if have
disabled it.
(Do you remember me, i am the guy using Apparmor)
I am using tmpfs on the RW layer and a compressed reiser4 filesystem on
the RO layer.
Now during boot i get the following kernal crash:

Fixing recursive fault but reboot is needed!
-----------------------------------------------------------------------------------------------------------------------------------
Do you have an idea, that could be the problem?
I already diffed the two aufs versions but i have not seen anything
special ...
Thanks,
Ulrich
